WARNING!
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD
TO OBTAIN POSITION INFORMATION.
CAUTION
When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when traveling to a waypoint, but will also visually check to make sure a clear, safe path to the waypoint is always available.
WARNING!
When a GPS unit is used in a vehicle, the vehicle operator is solely responsible for operating the vehicle in a safe manner. Vehicle operators must maintain full surveillance of all pertinent driving, boating or flying conditions at all times. An accident or collision resulting in damage to property, personal injury or death could occur if the operator of a GPS-equipped vehicle fails to pay full attention to travel conditions and vehicle operation while the vehicle is in motion.

Section 1:
Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin navigating and finding fish, but we have a favor to ask. Before you grab the unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performance from your commercial-quality combination fish finder and mapping GPS receiver.
First, we want to thank you for buying a Lowrance sonar/GPS unit.
Whether you're a first time user or a professional fisherman, you'll discover that your unit is easy to use, yet capable of handling demanding navigation and sonar tasks. When you team your unit with our custom mapping software MapCreate
6, you have an incredible combination.
With a full VGA color display, recording capability and remarkable resolution, you won't find another GPS/sonar unit with this much power and this many features for this price!
Our goal for this book is to get you on the water fast, with a minimum of fuss. Like you, we'd rather spend more time boating or fishing and less time reading the manual!
So, we designed our book so that you don't have to read the whole thing from front to back for the information you want. At the start (or end) of each segment, we'll tell you what content is coming up next. If it's a concept you're already familiar with, we'll show you how and where to skip ahead for the next important topic. We've also made it easy to look up any tips you may need from time to time. Here's how:
The manual is organized into 10 sections. This first section is an introduction to the LCX-104C sonar and GPS. It tells you the basics you need to know before you can make the unit look around and tell you where you are, or look below the surface to find some fish.
Section 2 will help you install your unit, the transducer and the GPS antenna module. We'll show you how to get the MultiMedia Card
(MMC) correctly installed inside the unit. We'll also tell you about some of the available accessories.
Section 3 covers Basic Sonar Operation . It will show you how easy it is to run your sonar, right out of the box. This section features a one-page
Sonar Quick Reference. (If you've already jumped ahead and figured out how to install the unit yourself, and you just can't wait any longer, turn to the Quick Reference on page 47 and head for the water with your unit!)
1
After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses more advanced Sonar Options and
Other Features .
When you come to a sonar menu command on the unit's screen, you can look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scanning through the sonar options in Section 4.
If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshooting .
The manual switches from sonar to navigation in Section 6, which introduces you to Basic GPS Operations . This section features a onepage GPS Quick Reference on page 103.
Section 6 contains short, easy-to-scan GPS lessons that follow one another in chronological order. They're all you'll need to know to find your way on the water quickly.
After you've learned the basics (or if you already have some GPS experience), you may want to try out some of the unit's many advanced navigation features. That brings us to Section 7, Advanced GPS Operations . This section contains the rest of the unit's GPS command functions, organized in alphabetical order.
When you come to a GPS menu command on the screen, you can look it up in the manual by skimming over the table of contents, just flipping through
Section 6 or scanning through the command portion of Section 7.
This unit is ready to use right out of the box, but you can fine tune and customize its operation with dozens of options. Since sonar is the unit's key feature, we put the main sonar options in Section 4. Some options, such as screen brightness settings, affect both sonar and GPS operations. We describe how to use those common options along with GPS options in Section 8, System Setup and GPS Setup Options . Section 8 is organized in alphabetical order .
In Section 9, we go into more detail on one of the unit's most remarkable
GPS capabilities — Searching. We'll introduce a search example in the
Basic GPS Operation section, but there are so many map items you can search for, we had to give this function its own section in the manual! For example, did you know your unit can look up business phone numbers, functioning as a virtual Yellow Pages? We’ll show you how in Section 9.
Finally, in Section 10, we offer Supplemental Material , including a list of the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on specifications to see just how much sonar and GPS power your unit contains. It's important to us (and our power users), but, if you don't care

How Your Sonar Works
Sonar has been around since the 1940s, so if you already know how it works, skip down to read about the relatively new technology of GPS.
But, if you've never owned a sonar fish finder, this segment will tell you the underwater basics.
Sonar is an abbreviation for SOund NAvigation and Ranging, a technology developed during World War II for tracking enemy submarines.
(Lowrance developed the world's first transistorized sportfishing sonar in
1957.) A sonar consists of a transmitter, transducer, receiver and display. In simple terms, here's how it finds the bottom, or the fish:
The transmitter emits an electrical impulse, which the transducer converts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object
5
(fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal.
The receiver amplifies this return signal, or echo, and sends it to the display, where an image of the object appears on the scrolling sonar chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object. The whole process repeats itself several times each second.
Your sonar unit can record a log of the sonar signals that scroll across the screen and save them to the MMC memory card. (These recordings are also called sonar charts or sonar graphs.) You can replay this sonar log in the unit using the Sonar Simulator function, or play it back on a personal computer using our free Sonar Viewer. The viewer is available for download from the Lowrance web site, www.lowrance.com.
You can save several different sonar log files, erase 'em and record new ones, over and over again. The size of your sonar recordings is only limited by the free space available on your MMC.
How Your GPS Works
You'll navigate faster and easier if you understand how this unit scans the sky to tell you where you are on the earth — and, where you're going. (But if you already have a working understanding of GPS receivers and the GPS navigation system, skip on ahead to Section 2, Installation
& Accessories on page 13. If you're new to GPS, read on, and you can later impress your friends with your new-found knowledge.)
First, think of your unit as a small but powerful computer. (But don't worry — we made the series easy to use, so you don't need to be a computer expert to find your way!) The unit includes a keypad and a screen with menus so you can tell it what to do. The screen also lets the unit show your location on a moving map, as well as point the way to your destination.
This gimbal-mounted unit uses an external antenna/receiver module, which makes the whole system work something like your car radio. But instead of your favorite dance tunes, this receiver tunes in to a couple of dozen GPS satellites circling the earth. (It will also listen in to the
WAAS satellites in orbit, but more about that in the upcoming segment introducing you to GPS and WAAS.)
Your unit listens to signals from as many satellites as it can "see" above the horizon, eliminates the weakest signals, then computes its location in relation to those satellites. Once it figures its latitude and longitude, the unit plots that position on the moving map shown on the screen.
The whole process takes place several times a second!
6
The performance doesn't stop there. Stored in the permanent memory of every unit is a basic background map of the entire world. We lock it in here at the factory — you can't change or erase this map.
The background map is suitable for many navigation chores, but for maximum accuracy and much more detail, you need our optional mapmaking software, MapCreate 6. Some unit features — such as searching for businesses and addresses — won't work without a custom
MapCreate map. There is so much detail in our background map (and even more in MapCreate) that we'll describe their contents and differences in Section 6, Basic GPS Operations , on page 91.
Another portion of the unit's onboard memory is devoted to recording
GPS navigation information, which includes waypoints, event marker icons, trails and routes. This lets you look back the way you came. Think of this data storage like the hard drive memory in a computer or a tape in a cassette tape recorder. You can save several different GPS data files, erase 'em and record new ones, over and over again. Like any computer file, these GPS Data Files (file format *.usr) can be shared between other Lowrance GPS or sonar/GPS units and even personal computers.
Your unit has one more thing in common with a personal computer.
Just as computers have a floppy disk drive for storing and exchanging files, this unit has a slot for an MMC (MultiMedia Card) or SDC (Secure Digital card) flash memory card. These solid-state memory devices are about the size of a postage stamp, but can hold data ranging from 8
MB to 256 MB in size. (Compare that to a floppy disk's 1.44 MB capacity!) The unit uses all that MMC space for two key GPS purposes. (The
MMC is also used to record sonar logs…see page 6.)
First, you can backup your onboard GPS Data Files by copying them to the MMC. Since the MMC is removable (like a floppy disk or a cassette tape), you can store these GPS Data Files on a personal computer equipped with an MMC card reader. (Or store them on a pocketful of
MMCs, if you don't have a computer.) Our MapCreate mapping software can save, edit or create its own GPS Data Files, which can be copied to the MMC and then loaded from the MMC into the unit's memory.
( NOTE: No matter where they come from, GPS Data Files must be loaded from the MMC into memory before the unit can use them.)
The other key GPS use for MMCs is storage of special high-detail, custom maps, which you can produce on your computer with our MapCreate software. These MapCreate custom maps contain much greater detail than the basic background map. These Custom Map Files (file format *.lcm) can also be shared between other Lowrance GPS or sonar/GPS units and personal computers. (For example, the exact same
7
MMC, custom map files and GPS data files can be used interchangeably between your gimbal-mounted LCX-104C and the hand-held iFINDER GPS receiver.)
The unit automatically reads Custom Map Files directly from the MMC or SDC. To use a custom map, all you need to do is slide an MMC containing a map into the unit.
Introduction to GPS and WAAS
Well, now you know the basics of how the unit does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page
13, so you can mount your unit and plug in the power. Or you might want to see how our text formatting makes the manual tutorials easy to skim. If that's the case, move on to "How to Use This Manual" on page
10. But, if you want to understand the current state of satellite navigation, look over this segment describing how GPS and its new companion
WAAS work together to get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by the United States Department of Defense. It was designed as a 24hour-a-day, 365-days-a-year, all weather global navigation system for the armed forces of the U.S. and its allies. Civilian use was also available at first, but it was less accurate because the military scrambled the signal somewhat, using a process called Selective Availability (SA.)
GPS proved so useful for civilian navigation that the federal government discontinued SA on May 2, 2000, after the military developed other methods to deny GPS service to enemy forces. Reliable accuracy for civilian users jumped from 100 meters (330 feet) under SA to the present level of 10 to 20 meters (about 30 to 60 feet.)
Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing overhead twice daily. A series of ground stations (with precisely surveyed locations) controls the satellites and monitors their exact locations in the sky. Each satellite broadcasts a low-power signal that identifies the satellite and its position above the earth. Three of these satellites are spares, unused until needed. The rest virtually guarantee that at least four satellites are in view nearly anywhere on Earth at all times.
The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level — also called altitude). This is called a 3D fix.
8
A minimum of three satellites are required to determine a 2D fix.
Remember, the unit must have a clear view of the satellites in order to receive their signals. Unlike radio or television signals, GPS works at very high frequencies. These signals can be easily blocked by trees, buildings, an automobile roof, even your body.
Like most GPS receivers, this unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for the unit to determine direction of travel, you must be moving and the faster, the better. This is not to say that it won’t work at walking or trolling speeds — it will. There will simply be more "wandering" of the data shown on the display.
GPS is plenty accurate for route navigation, but the U.S. Federal Aviation Administration has special needs for aircraft traffic control that go beyond basic GPS. The FAA has a plan under way to boost GPS performance even further with its Wide Area Augmentation System, or
WAAS. This GPS add-on will include a time control element that will help airliners fly closer together while avoiding collisions. In addition to carefully spacing airplanes along travel corridors, WAAS will eventually make instrument landings and takeoffs more accurate as it replaces existing aviation navigation systems.
Non-aviators can use WAAS signals to make their GPS navigation even more accurate. Your unit receives both GPS and WAAS signals. However, WAAS has some limits you should know about.
9
First, the U.S. government has not completed construction of the WAAS system, so it is not yet fully operational. The ground stations are in place, but only a few of the needed WAAS satellites have been launched.
WAAS can boost the accuracy of land GPS navigation, but the system is designed for aircraft. The satellites are in a fixed orbit around the
Equator, so they appear very low in the sky to someone on the ground in North America. Aircraft and vessels on open water can get consistently good WAAS reception, but terrain, foliage or even large man-made structures frequently block the WAAS signal from ground receivers.
You'll find that using your GPS receiver is both easy and amazingly accurate. It’s easily the most accurate method of electronic navigation available to the general public today. Remember, however, that this receiver is only a tool. Always have another method of navigation available, such as a map or chart and a compass.
Also remember that this unit will always show navigation information in the shortest line from your present position to a waypoint, regardless of terrain! It only calculates position, it can’t know what’s between you and your destination, for example. It’s up to you to safely navigate around obstacles, no matter how you’re using this product.
How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow
"keystrokes" appear as boldface type. So, if you're in a real hurry (or just need a reminder), you can skim the instructions and pick out what menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for those commands and other instructions:
Arrow Keys
The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor. The arrow keys also control a horizontal line depth cursor on the sonar screen. The arrow keys help you move around the menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← → .
Keyboard
The other keys perform a variety of functions. When the text refers to a key to press, the key is shown in bold, sans serif type. For example, the
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as
MENU .
10
Menu Commands
A menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: R OUTE P LANNING
. These indicate that you are to select this command or option from a menu or take an action of some kind with the menu item. Text that you may need to enter or file names you need to select are show in italic type, such as trail name .
Instructions = Menu Sequences
Most functions you perform with this unit are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading.
For example, instructions for navigating a trail would look like this:
1. From the Map Page, press MENU | MENU | ↓ to M
Y
T
RAILS
| ENT .
2. Press ↓ to Trail 1 | ENT | → | ↓ to N AVIGATE
| ENT .
3. You are asked to wait while it converts the trail into a route.
4. The wait message disappears and the unit begins showing navigation information along the trail. Now, begin moving and follow your unit's directions.
Translated into complete English, step 1 above would mean: "Start on the Map Page. Press the Menu key twice. Next, repeatedly press (or press and hold) the down arrow key to scroll down the menu and select
(highlight) the My Trails menu command. Finally, press the Enter key."
Step 2 would mean: "Press the down arrow key repeatedly to scroll to the trail named Trail 1, and press Enter. Next, press the right arrow key and then the down arrow key to highlight the Navigate command, then press Enter."

Installation & Accessories
Preparations
You can install the sonar and GPS systems in some other order if you prefer, but we recommend this installation sequence:
CAUTION:
You should read over this entire installation section before drilling any holes in your vehicle or vessel!
1. Determine the approximate location for the sonar/GPS unit, so you can plan how and where to route the cables for the antenna, transducer and power. This will help you make sure you have enough cable length for the desired configuration.
2. Determine the approximate location for the transducer and its cable route.
3. Determine the approximate location for the GPS antenna module and its cable route.
4. Determine the location of your battery or other power connection, along with the power cable route.
5. Install the transducer and route the transducer cable to the sonar/GPS unit.
6. Install the GPS antenna and route the antenna cable to the sonar/GPS unit.
7. Install the power cable and route it to the sonar/GPS unit.
8. Mount the sonar/GPS unit.
Transducer Installation
These instructions will help you install your Skimmer
transducer on a transom, on a trolling motor or inside a hull. These instructions cover both single- and dual-frequency Skimmer transducers. Please read all instructions before proceeding with any installation.
The smaller single-frequency Skimmers typically use a one-piece, stainless steel mounting bracket. The larger dual-frequency Skimmers typically use a two-piece, plastic mounting bracket. The trolling motor mount uses a one-piece plastic bracket with an adjustable strap.
These are all "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools.
13
Read these instructions carefully before attempting the installation.
Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed.
Remember, the transducer installation is the most critical part of a sonar installation.
Recommended Tools and supplies
If you prefer the option of routing the cable through the transom, you will need a 1" drill bit. A transom mount requires use of a high quality, marine grade above- or below-waterline caulking compound. The following installation types also call for these recommended tools and required supplies (supplies are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: none.
Dual-frequency transom installations
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood screws.
Single-frequency trolling motor installations
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic cable ties.
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult your boat dealer or manufacturer. Supplies: 100 grit sandpaper, good quality epoxy adhesive.
Selecting a Transducer Location
1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is to be mounted inside the hull, then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving.
NOTE:
Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good location on aluminum boats is between the ribs closest to the engine.
14
2. The transducer should be installed with its face pointing straight down, if possible.
3. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation.
4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.
CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed.

How low should you go?
For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps.
Transom
Transducer centerline
Hull bottom
Align transducer centerline with hull bottom.
15
However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes.
Move the transducer a little lower to help prevent this.
If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection.
There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom – the face – of the transducer rise above the bottom of the hull.
Shoot-thru-hull vs. Transom Mounting
Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer.
However, the shoot-thru-hull installation does have its drawbacks.
First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction.
Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds. Follow the procedure listed in the shoot-thru-hull installation section at the end of this lesson to determine if you can satisfactorily shoot through the hull.
TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING
The best way to install these transducers is to loosely assemble all of the parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground.
The following instructions sometimes vary depending on the mounting bracket that came with your transducer. Single-frequency Skimmers come with a one-piece stainless steel bracket, while dual-frequency
Skimmers come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model.
1. Assembling the bracket.
A. One-piece bracket: Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the
16
bracket with the letter "A" aligned with the dot stamped into the metal bracket. This position sets the transducer's coarse angle adjustment for a
14 ° transom. Most outboard and stern-drive transoms have a 14 ° angle.
Dot
Align plastic ratchets in bracket.
B.
Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet.
Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14
°
transom. Most outboard and stern-drive transoms have a 14 ° angle.

2. Aligning the transducer on the transom.
A.
One-piece bracket: Slide the transducer between the two ratchets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground.
If it does, then the "A" position is correct for your hull.
If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket.
Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3A. If it doesn't, repeat step 2A, but use a different alignment letter until you can place the transducer on the transom correctly.

B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" positions are correct for your hull.
If the transducer's face isn't parallel with the ground, remove and disassemble the transducer and ratchets. Place the ratchets into the bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem.
Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly.

4. Drilling mounting holes.
Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull!
Mark the center of each slot for the mounting screw pilot holes. You will drill one hole in the center of each slot.
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10 screws). For the two-piece bracket, use the #20 bit (for the #12 screws).

5. Attaching transducer to transom.
A. One-piece bracket: Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures.
For single-frequency Skimmer, route cable over bolt and through bracket. Side view shown at left and seen from above at right.
20
Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the caulking compound.
Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over tighten the lock nut!
If you do, the transducer won't "kick-up" if it strikes an object in the water.
Bottom of hull
Flat-bottom hull Deep-"vee" hull

6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires.
WARNING:
Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed.
If you need to drill a hole in the transom to pass the connector through, the required hole size be 1".
CAUTION:
If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the mounting screws.
21
7. Make a test run to determine the results.
If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull!
TROLLING MOTOR BRACKET INSTALLATION
(single-frequency only)
1. Attach the optional TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transducer.
(Note: The internal tooth washer is supplied with the TMB-S.)

2. Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the water. Tighten the strap securely.
3. Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.

TRANSDUCER ORIENTATION AND FISH ARCHES
If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds.

Partial fish arches
Transducer aimed too far forward

If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised.
NOTE:
Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation.
SHOOT-THRU-HULL PREPARATION
The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful
23
transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.
Fill with epoxy
Flotation material
Inner hull
Epoxy to hull first
Outer hull
Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass.
Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals.
WARNING:
Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications.
To choose the proper location for thru-hull mounting, anchor the boat in
60 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (You will need to turn off both automatic and ASP
.) Don't touch the controls once they've been set.
Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity.
Move the transducer around to find the best location. If the sensitivity control must be increased greatly to compensate, then the transducer should be mounted on the outside of the hull. If not, then mark the lo-
24
cation that shot through the hull the best and follow the instructions on the following pages for a shoot-thru-hull mounting.

Shoot-thru-hull Installation
1. Make sure the area is clean, dry and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with
100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding.
Spread epoxy here
Sand this surface
Epoxy transducer to hull.
2. Follow the instructions on the epoxy package and mix it thoroughly.
Do not mix it too fast, because it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull.
25
Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.
Speed/Temperature Sensors
This unit accepts up to three temperature sensors which can monitor surface water, live well, air and virtually any other temperature. If you want to use more than one temperature sensor or a speed sensor, you must purchase the optional MY-4X adapter cable. You also need to be careful when purchasing the temperature sensors, because each temperature sensor has its own fixed electronic "address." The sensors are labeled "Water," "T-2" (or Temp-2) and "T-3" (or Temp-3).
The first "Water" temperature sensor is built into the transducer. This is the sensor that measures surface water temperature. If you want two
(or more) temperature readings from other locations, you'll need to use the proper sensors. For example, you can't use two additional T-3 sensors. The sensors that fit this unit are:
• TS-1X This sensor will over-ride the temperature sensor built into the transducer and over-ride the temperature sensor in a ST-TGY combination sensor. (This sensor is not recommended.)
• TS-2X
•
TS-3X
•
SP-X
• ST-TGY
One sensor for "T-2" temperature display.
One sensor for "T-3" temperature display.
One speed sensor for "Speed" display.
This combination sensor will provide speed and temperature readings, but the temperature reading will be displayed as the "Water" temperature because it will over-ride the temperature sensor in the transducer. (This sensor is not recommended.)
See the wiring diagram on the following page for temperature and speed sensor combinations.

Optional Speed Sensor Installation
This unit can display speed and distance traveled; the feature requires a speed sensor which may or may not come packaged with your unit. (If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual.) The following instructions describe how to install the speed sensor.
Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit for pilot holes, screwdriver. Required supplies for this job include: four
#8 stainless steel wood screws (3/4" long), high quality, marine grade above- or below-waterline caulking compound.
First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline.
Once you've determined the proper location for the unit, place the sensor on the transom. The bottom of the bracket should be flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not included). Use a high quality, marine grade above- or below-waterline caulking compound to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.

Speed sensor mounting configuration: side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the transom and the sensor with the caulking compound. This will help ensure a smooth water flow.
Route the sensor's cable through or over the transom to the sonar unit.
If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8".
CAUTION:
If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the screws.
The sensor is now ready for use. Connect the sensor to the in-line connector on the MY-4X adapter cable. If you have any questions concerning the installation of the sensor, please contact your local boat dealer.
GPS Antenna/Receiver Module
This unit's package includes the LGC-12w GPS module. This device contains the unit's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with a 25-foot extension cable. This module can be mounted on a flat surface or pole, or a magnet is included for temporary mounting on any ferrous surface. (The
LGC-12s GPS module sold with earlier Lowrance equipment will work with your unit, but it will not receive WAAS signals.)
LGC-12 Module, bottom view (left) and top view (right).
29
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, route the cable to the unit, plug it in the center socket on the back and your system is ready to use. See the module's instruction sheet, publication part number 988-0147-39, for complete installation directions.
In an automobile, you may achieve good results by simply placing the external antenna on the top of the dash, at the base of the windshield.
A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in place. This may not work well if you have a cab-over design pickup truck camper or motor home. If dashboard reception is poor, simply relocate the antenna module elsewhere on the vehicle for a clearer view of the sky.
Power Connections
The unit works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery.
If possible, keep the power cable away from other boat or vehicle wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the inline fuse holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 6-amp fuse.

CAUTION:
Do not use this product without a 6-amp fuse wired into the power cable! Failure to use a 6-amp fuse will void your warranty.
This unit has reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly.
An optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Lowrance.
NMEA/DGPS Cable Connections
NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface on this unit and receive positioning information. The unit can exchange information with any device that transmits or receives NMEA
0183 data.
DGPS is an acronym for the Differential Global Positioning System.
DGPS supplements and boosts the accuracy of basic GPS. DGPS was developed by the U.S. Coast Guard, which is responsible for the system's operation in the United States. Since its creation, DGPS has become the international maritime standard for marine navigation.
The most popular DGPS system relies on a grid of ground-based transmitters that send correction signals to DGPS receivers. These in turn, connect to the GPS receiver (such as the LCX-104C). Lowrance offers an optional DGPS receiver for your unit.
See the following diagrams for general wiring connections. Read your other product’s owner’s manual for more wiring information.
NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the unit has two NMEA 0183 version
2.0 communication ports. Com port one (Com-1) can be used to receive
NMEA format GPS data or DGPS data. Com-1 can also transmit NMEA format GPS data to another device. Com-2 is for NMEA output only.
The three wires for the com port are combined with the two power wires and the speaker wires to form the power/data cable (see the drawing on page 33). Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Com-2 uses the blue wire for transmit.

Mounting the Unit: Bracket or In-Dash
You can install the unit on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash. For an in-dash mount, consult the factory customer service department. Service contact information is inside the back cover of this manual.
Bracket Installation
Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power, transducer and GPS antenna/receiver module cables. (A drawing on the next page shows the dimensions of a gimbal-mounted unit.)
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.

Install the gimbal bracket. Orient the bracket so the arms slope toward the front of your unit.
34
Once a location is determined, use the bracket as a template and mark the mounting holes and the hole for the cables. Drill a 1-inch (25.4 mm) hole in the dash for the power, transducer and antenna cables. Screw the bracket to the mounting surface.
To pass all connectors through the 1" hole, first pass the transducer connector up through the hole from under the dash, followed by any accessory cables. Next, pass the power cable's bare-wire end down though the hole from the top.
If you wish, you can fill in the hole around the cables with a good marine caulking compound. Be sure to leave enough slack in the cables to allow tilting the unit.
Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers, attach the cables and the unit is ready to use.
MMC or SDC Memory Card Installation
Your unit uses MultiMedia Cards to store information, such as sonar logs, custom maps, waypoints, trails and other GPS data. The unit can also use Secure Digital Cards (SD card or SDC) to store data. The unit can use up to two cards at the same time; an MMC and an SDC can be used together at the same time.
NOTE:
Throughout this manual, we will use the term MMC, but just remember that your unit can use an MMC or SDC to store data.
Both of these solid-state flash memory devices are about the size of a postage stamp. An SD card is slightly thicker than an MMC. As this manual went to press, MMCs were available in storage capacities of 8
MB, 16 MB, 32 MB and 64 MB. SD cards were available in capacities of
8 MB, 16 MB, 32 MB, 64 MB, 128 MB and 256 MB.
Additional MMC cards are available from LEI Extras; see ordering information inside the back cover of this manual. MMCs and SD cards are also available at many camera and consumer electronics stores.
The two MMC slots are located in compartments on the front of the case. The water-proof compartment doors are located at the lower right corner. The following figure shows a close-up of one compartment with the door opened.

2. Use a thumbnail or fingernail to grab the groove in the bottom of the
MMC. See the figure above for the groove location.
3. Drag the MMC from the slot.
To add an MMC or SDC
1. Open the card compartment door.
2. Grasp the bottom of the MMC and push the top of the card into the slot. Once the card is started, use your fingernails to slide it the rest of the way to the left, until it is firmly seated in the slot.
3. Close the compartment door and fasten the thumb screw finger tight.
Other Accessories
Screen Cleaning Kit
Your unit's display screen is equipped with a special anti-glare filter that improves readability in a wide range of lighting conditions. A bottle of filter cleaning fluid is included with your unit. Additional bottles of cleaner may be purchased from your dealer or LEI Extras, the accessory source for Lowrance equipment. Accessory ordering information is on the inside back cover of this manual.
WARNING:
Improperly cleaning your unit's screen can result in damage to the anti-glare filter. This type of damage is not covered by the warranty. To protect the screen and
36
its anti-glare properties, always use the special cleaner available from your dealer or LEI Extras.
To remove fingerprints, water spots, dust or other grime from the screen, hold the bottle about 6 inches (15 cm) from the screen and spray. Wipe immediately with a clean, dry, lint-free cloth.
MMC and MapCreate
Other available accessories include MMC cards, MMC card readers and
MapCreate™ 6 custom mapping software for your computer. MMC card readers are available in USB and parallel port versions. This unit ships with the MapCreate accessory pack, which includes the software, one
USB card reader and one 16 MB MMC. See the MapCreate manual and the card reader instruction sheet for installation information.
MapCreate™ 6 CD-ROM, left; MMC card reader for USB ports, right.
Switch Boxes
Two switch boxes are available for this unit. The SB-7X transducer switch box switches two transducers to one sonar unit. The SB-8X transducer switch box switches two sonar units to one transducer.
If these accessories are not available from your dealer, see the accessory ordering information on the inside back cover of this manual. Visit our web site for a complete listing of all the available accessories for your unit.
External Speaker
Your unit can play sounds to an external speaker. This feature can be convenient any time you are away from the unit – especially in a larger boat – but still want to hear its alarms. You might install a small speaker at the stern of your boat so you won't miss a dangerous Shallow Alarm while fishing, or put one in your galley so you can hear the
GPS Arrival Alarm.
37
You can purchase an external speaker at your nearest audio electronics store. The unit is designed to work with most speakers, but make sure to buy one that meets these minimum requirements:
• Minimum 8-ohm resistance
• Minimum 5-watt power
In your vessel or vehicle, mount the speaker wherever you want to hear your unit's sounds. (Follow the speaker's installation instructions).
Next, connect the speaker to your unit. The external audio wires are the labeled red and black wires in the power/data cable. The speaker's input cable should have two exposed wires: a positive and a negative
(ground). Connect the speaker's positive wire to the unit's red speaker wire, and the speaker's negative (ground) wire to the unit's black speaker wire.
The unit should automatically begin to play any active sounds through the attached speaker.
Face Cover
Your unit comes with a white protective cover that snaps on and off the front of the unit. When the unit is in storage, the cover protects the screen from damage that can result from long-term exposure to the sun's ultraviolet rays. This cover is intended for use when your unit and the vehicle it's mounted in are idle.
WARNING:
When the unit is mounted in an unprotected area, such as an open boat cockpit, the protective face cover must be removed when the vehicle is moving at high speed.
This includes towing a boat on a trailer at highway speeds. Otherwise, wind blast can pop off the cover.
Now that you have your unit installed, move on to Sec. 3, Basic Sonar
Operations . There, we'll present a series of step-by-step tutorials to teach you the basics of your sonar operation.
NOTE:
When you first turn the unit on, the Map Page appears. If you'd rather start learning about GPS operation first, turn over to Sec. 6,
Basic GPS Operations . (Remember, you don't need to read this manual from cover-to-cover to get going. We designed it so you can skip around to the section you want to read.)

You can customize how the Sonar Page displays its pictures and other data in many ways. Your unit also includes several special sonar features and options that can help you better interpret the underwater scene.
We'll discuss all of those features and options in Sec. 4, but to show you how easy the unit is to operate, the following page contains a simplified,
10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.
46
LCX-104C Sonar Quick Reference
1. Mount the transducer, antenna and unit. Connect the unit to electric power and the transducer. (If GPS operation is desired, connect GPS antenna, too.) Make sure the MMC is in. (See complete installation details beginning on page 13.)
2. Launch your boat.
3. To turn on the unit, press and release PWR key.
4. Opening screen displays Map Page. Rotate through the four main
Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar
Page) by pressing PAGES |
←
or
→
to select Page Name | EXIT . Switch
Pages to display Sonar Page.
5. If GPS data is desired, wait while unit locates satellites and calculates current position. When the unit acquires position, a tone sounds and a position acquired message appears.
6. With position acquired (if desired), head for your fishing grounds.
Your unit will automatically display digital depth and surface water temperature in the top left corner of the screen.
The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water. You can change the display by:
Zoom in to enlarge the chart for more detail: press ZIN .
Zoom out to return to full chart mode: press ZOUT .
7. Watch the display for the appearance of fish arches. When you see arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart.
8. Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. Press MENU | ↓ to D EPTH C URSOR
| ENT .
Press
↓
to align the cursor line with the fish arch. The exact depth appears in a box at the right end of the cursor line. To clear the cursor, press EXIT .
9. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom.
10. To turn off the unit, press and hold PWR key for three seconds.
47
Sonar Operations
As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working.
As you're learning the basics, there is one setting you might want to tinker with from time to time — Sensitivity.
Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present.
As you change the sensitivity setting, you can see the difference on the chart as it scrolls.
Fig. 1 Fig. 2
Fig. 3 Fig. 4
These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 75 percent. Fig.
3: Sensitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.
You can change the sensitivity level whether you are in Auto Sensitivity mode or Manual Sensitivity mode. The adjustment method works the same in both modes, but it gives you slightly different results.
48
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on.
You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting. In this unit, auto mode will let you increase sensitivity to
100 percent, but the unit will limit your minimum setting. This prevents you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control — you have complete manual control of the car's speed. In this unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on water conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 50 percent or less!
Try adjusting sensitivity in both auto and manual modes to see how they work.
To adjust sensitivity:
1. Press MENU | ENT .
2. The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity; press ↑ to increase sensitivity. When it's set at the desired level, press
EXIT . (When you reach the maximum or minimum limit, a tone sounds.)
At left, Sonar Menu with Sensitivity command selected. At right, the
Sensitivity Control Bar.
NOTE:
If you want to change the sensitivity in Manual Mode, first turn off
Auto Sensitivity: from the Sonar Page, press MENU | ↓ to A
UTO
S ENSITIVITY
| ENT | ↑ to S ENSITIVITY
| ENT . Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the desired level, press EXIT .
49
Important Tip:
While you are experimenting and learning, it's possible to scramble the settings so that the sonar picture disappears from your screen.
If that happens, remember that it's easy to switch back to full automatic operation by simply restoring the factory auto settings.
Here's how:
To Restore Factory Settings
1. Press MENU | MENU | ↓ to S YSTEM S ETUP
| ENT | ↓ to R ESET O P-
TIONS
| ENT .
2. The unit asks if you want to reset all the options. Press ← to
Y ES
| ENT . All options are reset, and the unit reverts back to the Map
Page at the 4000 mile zoom range. (Any recorded sonar logs or GPS data will be unchanged.)
Fish Symbols vs. Full Sonar Chart
You may have noticed in the quick reference that we used fish arches in full sonar chart mode for our example, and not the popular Fish I.D.
fish symbol feature. Here's why.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations.
Your sonar unit's microprocessor is remarkably powerful, but it can be fooled. Some of the echoes calculated to be fish could be tree limbs or turtles! To see what's under your boat in maximum detail, we recommend you turn off Fish I.D. and begin learning to interpret fish arches.
Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen.
Then, you can turn on Fish I.D. and the audible fish alarm. When that lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, in one case fisherman in San Francisco Bay saw clouds of clutter in the water but no fish arches. When a down rigger was pulled up, it brought up several small jellyfish. The fisherman switched their Lowrance sonar to Fish I.D., which screened out the schools of jellyfish and clearly showed the game fish there as fish symbols.

Section 4:
Sonar Options & Other Features
Material in this section is arranged in alphabetical order.
ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference. This automatic feature gives you the best display possible under most conditions.
The ASP feature is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display.
The ASP feature has four settings — Off, Low, Medium and High. If you have high noise levels, try using the "High" ASP setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit with the high ASP setting.
There are times when you may want to turn the ASP feature off. This allows you to view all incoming echoes before they are processed by the
ASP feature.
At left, Sonar Menu with Sonar Features selected. In the Sonar Features menu, Noise Rejection is selected with ASP in the default low setting.

Alarms
This unit has three different types of sonar alarms. The first is the Fish
Alarm. It sounds when the Fish I.D.
feature determines that an echo is a fish.
Another alarm is the Zone Alarm, which consists of a bar on the side of the screen. Any echo on the chart that appears inside this bar triggers this alarm.
The last alarm is the Depth Alarm, which has both a Shallow and a
Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert or for navigation.
Depth A l arms
The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It will continue to sound until the bottom goes deeper than 10 feet.
The deep alarm works just the opposite. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. These alarms can be used at the same time or individually.

Calibrate Speed
The speed sensor can be calibrated to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the speed is off. You will enter this percentage in a moment.
56
For example, if you figure the sensor is reading 10 percent faster than actual speed, you will enter – 10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in the window.
A good way to gauge your speed sensor's performance is to compare its reading with the ground speed measured by your unit's GPS functions.
When you make a run to compare GPS ground speed to speed sensor speed, perform your test in relatively calm water free of current, if possible. (Unless, of course, you are taking the current speed into consideration when making your calculation.) After you have a correction figure, here's how to enter it:

2. Enter the number you calculated earlier: press ↑ or ↓ to change the first character (+ or –), then press → to move the cursor to the next number and repeat until the percentage is correct, then press EXIT .
Chart Speed
The rate that echoes scroll across the screen is called the chart speed.
The default is maximum; we recommend that you leave the speed set there for virtually all fishing conditions.
However, you might consider experimenting with chart speed when you are stationary or drifting very slowly. You may sometimes achieve better images as you slow down the chart speed to match how fast you are moving across the bottom.
If you are at anchor, ice fishing or fishing from a dock, experiment with a chart speed around 50 percent. If you are drifting slowly, try a chart speed around 75 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line instead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return.
At left, Sonar Page menu with Chart Speed command selected.
At right, Chart Speed Control Bar.
57
If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at higher speed. To change chart speed:
1. From the Sonar Page, press MENU |
↓
to C HART S PEED
| ENT .
2. The Chart Speed Control Bar appears. Press ↓ to decrease chart speed; press ↑ to increase chart speed.
3. When it's set at the desired level, press EXIT .
ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
"paints" a brighter color on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow, colored line (dark blue tinged with red or a little yellow.) Since fish are among the weakest echoes, they show up mostly as blue arches. A hard bottom or other relatively hard target returns a strong signal which causes a wider brightly colored line (reddish yellow to bright yellow.)
If you have two signals of equal size, one with red to yellow color and the other without, then the target with brighter color (yellow) is the stronger signal. This helps distinguish weeds from trees on the bottom, or fish from structure.
ColorLine is adjustable. Experiment with your unit to find the Color-
Line setting that's best for you.

Depth Range - Upper and Lower Limits
Virtually any segment of the water column can be displayed by using the upper and lower limit feature. This lets you pick the shallow and deep depth range limits that are shown on the screen, provided there is at least 10 feet between the upper and lower limit you select. For example, a range from 12 feet to 34 feet could be used.
61
Changing the upper and lower limits gives you far greater control over the depth range. This feature lets you "zoom in" the display in almost unlimited combinations. Nearly any segment of the water column, from the surface to the bottom can be shown. This enlarges the sonar targets to best suit your fishing needs and water conditions.

FasTrack
This feature automatically converts all echoes to short horizontal lines on the display's far right side. The graph on the rest of the screen continues to operate normally. FasTrack gives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or when you're fishing at anchor. When the boat is not moving, fish signals are long, drawn out lines on a normal chart display. FasTrack converts the graph to a vertical bar graph that, with practice, makes a useful addition to fishing at a stationary location.

Fish I.D.
(Fish Symbols & Depths)
The Fish I.D. feature identifies targets that meet certain conditions as fish. The microcomputer analyzes all echoes and eliminates surface clutter, thermoclines, and other signals that are undesirable. In most instances, remaining targets are fish. The Fish I.D. feature displays fish symbols on the screen in place of the actual fish echoes.
There are several fish symbol sizes. These are used to designate the relative size between targets. In other words, Fish I.D. displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so on.
The sonar's microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outwards from a group of limbs is the hardest object for the
Fish I.D. feature to distinguish from fish.
You may see fish symbols on the screen when actually, there are no fish. The reverse is also true. The illustrations on the next page show how Fish I.D. can actually miss fish that are present.
63
Does that mean Fish I.D. is broken? No — the feature is simply interpreting sonar returns in a specific way to help take some of the work out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully
"see" beneath the boat under varied water and fishing conditions. So, practice with the unit in both the Fish I.D. mode and without to become more familiar with the feature. The default for Fish I.D. is off.

Frequency (Change Transducer Frequency)
(Dual-Frequency Transducers only)
A dual-frequency transducer operates with both 200 kHz and 50 kHz.
The 200 kHz frequency has a 12
°
cone angle and the 50 kHz frequency has a 35 ° cone angle.
The default frequency is 200 kHz, which is best for use in shallow water
(about 300 feet or less). This frequency is the best choice for about 80 percent of the fresh and salt water sport fishing applications. When you get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz frequency is the best choice.
65
The 200 kHz transducer will give you better detail and definition, but less depth penetration. The 50 kHz transducer will give you greater depth penetration, but a little less detail and less definition. (Remember, all sonar units typically read deeper in fresh water than in salt water.)
There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait.

Ping Speed & HyperScroll
Ping Speed controls the rate at which the transmitter and transducer broadcast sonar sound waves — pings — into the water. The unit has a default ping speed of 50 percent. At normal boating speeds, this automatically provides enough return echoes to refresh the screen and scroll the chart at maximum chart speed.
69
However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature.
When you change the Ping Speed to any setting greater than 50 percent, the unit automatically enters HyperScroll mode.
These faster ping rates allow you to maintain a high-detail picture on the screen, and the screen refresh rate and chart scroll speed can keep pace with the boat as it moves quickly over the bottom terrain.
When using HyperScroll, you may also need to manually decrease the sensitivity for optimum performance. Depending on water depth and other conditions, HyperScroll may cause a second bottom echo to return to the transducer during the next ping cycle, or sounding. This can result in a large amount of clutter appearing on the screen. If this occurs, just decrease the sensitivity to a level that eliminates the clutter. When you turn HyperScroll off, you can return to your original sensitivity level.

Set Keel Offset
This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance displayed by the digital depth, chart depth scale, chart cursor or fish symbols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the actual depth is 31 feet.
On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel.
Keel Offset lets you calibrate the digital depth: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the transducer to the lowest part of the boat. In this example, we will use 3.5
feet. This will entered as a negative 3.5 feet, which makes the depth indicators perform as if the transducer's lower in the water than it really is.

NOTE:
If knowing the exact depth of water beneath the keel is less important, you can calibrate the depth indicators so that they show the actual water depth from surface to bottom. To do this, first measure the distance from the face of the transducer up to the surface (the water line on the boat). In this example, we will use 1.5 feet. This will be entered as a positive 1.5 feet, which makes the depth indicators perform as if the transducer's higher in the water than it really is.
1. Press MENU | MENU | ↓ to S ET K EEL O FFSET

4. Press → to the second number, them press ↑ to change the number to 5, then press EXIT . The depth indicators now accurately show the water depth from surface to bottom.
Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. Sensitivity can be adjusted, because water conditions vary greatly. A low sensitivity level (from zero to 50 percent) excludes much of the bottom information, fish signals, and other target information.
High sensitivity levels let you see this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Grayline and some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in the automatic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more power. This gives it the capability to show fish and other detail.
However, situations occur when it becomes necessary to increase or decrease the sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is indicated. Or, wave action and boat wakes can create enough tiny air bubbles to clutter much of the water column. In that case, a decrease in sensitivity is indicated to reduce some of the clutter.
The control bar used to adjust sensitivity up or down is the same whether the unit is in the automatic or manual mode. In automatic you can adjust sensitivity up to 100 percent but the unit will limit your minimum setting. In auto, the unit will continue to make small adjustments, allowing for the setting you selected.
In manual mode, you have complete control over sensitivity, with the ability to set it anywhere from zero to 100 percent. Once you select a level in manual, the unit will continue to use that exact sensitivity setting until you change it or revert to auto mode.
To adjust sensitivity in auto mode:
1. Press MENU | ENT .

NOTE:
If you turn on your unit before attaching a transducer, it may enter a demo mode. The words "demo mode" flash on the bottom of the screen and a sonar chart plays much like the simulator. Unlike the simulator, the demo mode is for demonstration only, and will automatically stop as soon as you turn on the unit with a transducer attached. The simulator will continue to function normally.
82
Stop Chart
If you are running multiple units on a boat or using this unit in a car, there are times when you may want to turn off the sonar. This command turns off the sonar and stops the chart from scrolling. Sonar restarts automatically each time you turn on your unit.
Press MENU |

To turn on sonar and start the chart scrolling again, repeat the above step.
Sonar Menu with Stop Chart command selected. The box is unchecked, indicating that the chart is scrolling across the screen.
Surface Clarity
The markings extending downward from the zero line on the chart are called "surface clutter." These markings are caused by wave action, boat wakes, temperature inversion and more.
The surface clarity control reduces or eliminates surface clutter signals from the display. It does this by changing the sensitivity of the receiver, decreasing it near the surface and gradually increasing it as the depth increases.
There are three levels of surface clarity available: low, medium, or high.
It can also be turned off. The default level is off.
To adjust the Surface Clarity level:

Zoom & Zoom Bar
"Zooming" the display is a common, fast and easy method used to enlarge small detail, fish signals and the bottom with its associated structure. This unit lets you zoom the display quickly and easily by pressing the Zoom In key, ZIN .
Pressing ZIN once doubles the size (2X) of all echoes on the screen.
Pressing it again quadruples the size of the echoes (4X). The zoom bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed.
84
For example, pressing the ZIN key once will enable a 2X zoom which will show all echoes that are between the top and bottom of the 2X zoom bar. Pressing the key again will give a 4X zoom and only the echoes between the top and bottom of the 4X bar will show on the screen.
Press the Zoom Out key, ZOUT , to return the display to the normal mode.
At left, Sonar Page, normal view. Center, same view zoomed to 2X.
Right, same view zoomed to 4X
Zoom Pan
Your unit has the handy ability to quickly zoom in on any portion of the water column with just the touch of an arrow key. The Zoom Pan feature lets you rapidly move the zoomed area up and down to different depths.
By "pointing" your zoom at different portions of the chart as it scrolls, you can get a good, close-up look at structure or cover below you.
To use Zoom Pan, switch to a manual depth Range setting (see page 61) and turn on 2X or 4X Zoom. Then, simply press ↑ or ↓ to pan up and down the water column.

Section 5:
Sonar Troubleshooting
If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual.
Unit won't turn on:
1. Check the power cable's connection at the unit. Also check the wiring.
2. Make certain the power cable is wired properly. The red wire connects to the positive battery terminal, black to negative or ground.
3. Check the fuse.
4. Measure the battery voltage at the unit's power connector. It should be at least 11 volts. If it isn't, the wiring to the unit is defective, the battery terminals or wiring on the terminals are corroded, or the battery needs charging.
Unit operates only in demo mode:
The transducer or antenna module has not yet been connected or has been disconnected. To leave demo mode, make sure that either the transducer or the antenna is securely connected before turning the unit on.
Unit freezes, locks up, or operates erratically:
1. Electrical noise from the boat's motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and transducer cables away from other electrical wiring on the boat may help. Route the sonar unit's power cable directly to the battery instead of through a fuse block or ignition switch
2. Inspect the transducer cable for breaks, cuts, or pinched wires.
3. Check both the transducer and power connectors. Make certain both are securely plugged in to the unit.
Weak bottom echo, digital readings erratic, or no fish signals:
1. Make certain the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. Do NOT use RTV silicone rubber adhesive or Marine-Tex epoxy.
2. Electrical noise from the boat's motor can interfere with the sonar.
87
This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display.
3. The water may be deeper than the sonar's ability to find the bottom.
If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear.
4. Check the battery voltage. If the voltage drops, the unit's transmitter power also drops, reducing its ability to find the bottom or targets.
Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving
1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is cavitation.
2. Electrical noise from the boat's motor can interfere with the sonar.
This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. Try using resistor spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat.
No fish arches when the Fish I.D. feature is off:
1. Make certain the transducer is pointing straight down. This is the most common problem if a partial arch is displayed.
2. The sensitivity may not be high enough. In order for the unit to display a fish arch, it has to be able to receive the fish's echo from the time it enters the cone until it leaves. If the sensitivity is not high enough, the unit shows the fish only when it is in the center of the cone.
3. Use the Zoom feature. It is much easier to display fish arches when zoomed in on a small range of water than a large one. For example, you will have much better luck seeing fish arches with a 30 to 60 foot range than a 0 to 60 foot range. This enlarges the targets, allowing the display to show much more detail.
4. The boat must be moving at a slow trolling speed to see fish arches.
If the boat is motionless, fish stay in the cone, showing on the screen as straight horizontal lines.
88
NOISE
A major cause of sonar problems is electrical noise. This usually appears on the sonar's display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit to operate erratically, or not at all.
To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make sure the engine is also off. Turn your sonar on, then turn off Noise Reject
[also known as the ASP feature (Advanced Signal Processing)].
Sensitivity should be set at 90-95 percent. There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonar's display. For example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off.
If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem. You can usually reroute the sonar unit's power cable and transducer cable away from the wiring that is causing the interference. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the sonar's wires away from it. You may need to route the sonar unit's power cable directly to the battery to isolate it from other wiring on the boat.
If no noise displays on the sonar unit from electrical equipment, then make certain everything except the sonar unit is turned off, then start the engine. Increase the RPM with the gearshift in neutral. If noise appears on the display, the problem could be one of three things; spark plugs, alternator, or tachometer wiring. Try using resistor spark plugs, alternator filters, or routing the sonar unit's power cable away from engine wiring. Again, routing the power cable directly to the battery helps eliminate noise problems. Make certain to use the in-line fuse supplied with the unit when wiring the power cable to the battery.
When no noise appears on the sonar unit after all of the above tests, then the noise source is probably cavitation. Many novices or persons with limited experience make hasty sonar installations which function perfectly in shallow water, or when the boat is at rest. In nearly all cases, the cause of the malfunction will be the location and/or angle of the transducer. The face of the transducer must be placed in a location that has a smooth flow of water at all boat speeds. Read your transducer owner's manual for the best mounting position.

Page and the Sonar Page. They are accessed by pressing the PAGES key, then using → or ← to select a Page. (Clear the Pages Menu by pressing
EXIT .)
Pages Menu, showing some Map display options.
Sonar Page
The Sonar Page displays the sonar chart, a view of the water column from the surface to the bottom. The chart scrolls across the screen from right to left, displaying signal echoes that represent fish, structure and the bottom. The Sonar Page is discussed in detail in Sec. 3. To get to the Sonar Page: Press the PAGES key, then use → or ← to select S ONAR
.
(Clear the Pages Menu by pressing EXIT .)
Satellite Status Page
The Satellite Status Page, shown, provides detailed information on the status of the Unit's satellite lock-on and position acquisition. To get to the Satellite Status Page: Press the PAGES key, then use → or ← to select S TATUS
. (Clear the Pages Menu by pressing EXIT .)
94
No matter what Page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate that satellite lock has been lost and there is no position confirmed. The Satellite Status Page shows you the quality and accuracy of the current satellite lock-on and position calculation.
WARNING:
Do not begin navigating with this unit until the numbers have stopped flashing!
Satellite Status Page. Left view indicates unit has not locked on to any satellites and does not have a fix on its position. Right view shows satellite lock-on with a 3D position acquired
(latitude, longitude and altitude), and WAAS reception.
This screen shows a graphical view of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents
45° above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north.
The GPS receiver is tracking satellites that are in light blue. The receiver hasn't locked onto a satellite if the number is dark blue, therefore it isn't being used to solve the position.
Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has twelve channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving the signals from the satellite.
The "Estimated Position Error" (horizontal position error) shown in the upper left corner of the screen is the expected error from a benchmark location. In other words, if the EPE shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. This also gives you an indicator of the fix quality the unit cur-
95
rently has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid.
The Satellite Status Page has its own menu, which is used for setting various options. (Options and setup are discussed in Sec. 8.) To access the Satellite Status Page Menu, from the Status Page, press MENU .
Navigation Page
This screen has a compass rose that not only shows your direction of travel, but also the direction to a recalled waypoint. To get to the Navigation Page: Press PAGES |

When navigating to a waypoint, the Navigation screen looks like the following figure. Your ground speed, track, distance and bearing to waypoint, and course are all shown digitally on this screen.
96
NOTE:
Remember, when the Speed, Track and Position information displays are flashing, satellite lock has not been achieved and no position fix has been determined. A question mark will also flash on the present position arrow in the center of the compass rose.
Speed (ground speed) is the velocity you are making over the ground. (If you wish, you can customize the Speed window to display Closing
Speed instead. Closing Speed is also known as velocity made good. It's the speed that you're making toward the waypoint. For instructions, see the Customize Page Displays entry in Sec. 8.)
Track is the heading, or the current direction you are actually traveling. Bearing is the direction of a line-of-sight from your present position to the destination. No matter what direction you are steering, the
Bearing window shows the compass direction straight to the destination from your location at the moment. Distance shows how far it is to the waypoint you're navigating toward.
The Off Course window shows the current cross track error. This shows the distance you are off-course to the side of the desired course line. The course line is an imaginary line drawn from your position when you started navigating to the destination waypoint. The course line is shown on the Navigation Page screen (and the Map Page screen) as a red line.
The cross track error range is shown on the compass rose as a wide, white, corridor enclosing the course line. The outer edges of this white corridor represent lines that show the current cross track error range.
The default for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross track error line, then you are 0.20 miles to the right of the desired course. You need to steer left to return to the desired course. You can use the ZIN or ZOUT keys to change the cross track error range.
A circular symbol depicting your destination (waypoint) appears on the screen as you approach the waypoint, as shown on the screen in the following figure.
Travel Time is the time that it will take to reach your destination at your present closing speed. (You can also customize the time window to show Arrival Time instead. Arrival Time is the local time it will be when you arrive at the destination, based upon your present closing speed and track.)

The Navigation Page has its own menu, which is used for some advanced functions and for setting various options. (Options and setup are discussed in Sec. 8.) To access the Navigation Page Menu, from the
Navigation Page, press MENU .
Map Page
The Map Page screens show your course and track from a "bird's-eye" view. By default, this unit shows the map with north always at the top of the screen. (This can be changed. See the topic Map Orientation , in
Sec. 8.) If you're navigating to a waypoint, the map also shows your starting location, present position, course line and destination. You don't have to navigate to a waypoint, however, to use the map.
Map Page is the default screen that appears when you turn on the unit.
To get to the Map Page from another page: Press PAGES | → or ← to
M AP
| EXIT . When the Map Page is displayed, a screen similar to the following figures appears.
The arrow in the center of the screen is your present position. It points in the direction you're traveling. The magenta line extending from the back of the arrow is your plot trail, or path you've taken.
98
Destination name
The map zoom range is the distance across the screen. This number shows in the lower right corner of the screen. In the first example figure below, the range is 4,000 miles from the left edge of the map to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its coverage area and the amount of mapping detail shown. There are 37 available map zoom ranges, from 0.05 miles to 4,000 miles.
Far left, Map Page opening screen. Center, zoomed to 100 miles and right, zoomed to 15 miles. Over Zoomed means you have reached the detail limits in an area covered only by the basic background map.
Zooming in any closer will reveal no more map details because a highdetail custom map has not been loaded on the MMC for this area.
If you're using only the factory-loaded background map, the maximum zoom range for showing additional map detail is 20 miles. You can continue to zoom in closer, but the map will simply be enlarged without revealing more map content (except for a few major city streets.) Load your own high-detail custom map made with MapCreate, and you can zoom in to 0.05 miles with massive amounts of accurate map detail.
Map Pages with high-detail MapCreate map of an urban area loaded on the MMC. At left, arterial streets appear at the 6 mile zoom range, with a few Point of Interest icons visible. Center, numerous dots representing
Points of Interest become visible at the 3 mile range, along with minor streets. Right, at the 0.6 mile zoom, you can see an interstate highway with an exit, major and minor streets as well as Point of Interest icons.
Background map vs. MapCreate map content
The background map includes: low-detail maps of the whole world (containing cities, major lakes, major rivers, political boundaries); and medium-detail maps of the United States.
99
The medium-detail U.S. maps contain: all incorporated cities; shaded metropolitan areas; county boundaries; shaded public lands (such as national forests and parks); some major city streets; Interstate, U.S.
and state highways; Interstate highway exits and exit services information; large- and medium-sized lakes and streams; and more than 60,000 navigation aids and 10,000 wrecks and obstructions in U.S. coastal and
Great Lakes waters
MapCreate custom maps include massive amounts of information not found in the background map. MapCreate contains: the searchable
Points of Interest database, all the minor roads and streets, all the landmark features (such as summits, schools, radio towers, etc.); more rivers, streams, smaller lakes and ponds and their names.
What's more important is the large scale map detail that allows your
GPS unit to show a higher level of position accuracy. For example, the background map would show you the general outline and approximate shape of a coastline or water body, but the higher detail in MapCreate shows the shoreline completely and accurately (finer detail). Many smaller islands would not be included in the background map, but are, of course, in MapCreate.

When the map is zoomed out far enough, most POIs appear as square dots. As you zoom in closer, the symbols become readable icons. In the
0.6 mile zoom example at right, the cursor has selected the Cupps Café
POI, which triggers a pop-up box with the POI name. This pop-up box works on POIs at any zoom range.
Tip:
In some urban areas, businesses are so close to one another that their POI icons crowd each other on the screen. In the preceding figure, you can see a jumbled pile of POIs along Highway 34. You

can reduce screen clutter and make streets and other map features easier to see by simply turning off the display of POIs you're not watching for. (To see how, check the text on Map Detail Category
Selection, page 147. It shows how to use the Map Categories Drawn menu to turn individual POI displays off and on.) Even though their display is turned off, you can still search for POIs and their icons will pop-up when your unit finds them for you.
The Map Page has its own menu, which is used for several functions and for setting various options. To access the Map Page Menu, from the

GPS Quick Reference
Start outdoors, with a clear view of the open sky. As you practice, try navigating to a location at least a few blocks away. While you're learning, navigation in too small an area will constantly trigger arrival alarms.
1. Connect the unit to electric power and the antenna module. Make sure the MMC is in. (See complete installation details beginning on page 13.)
2. To turn on the LCX-104C, press and release PWR key.
3. Opening screen displays map of North America at the 4,000 mile zoom range. Rotate through the four main Page screens (Map Page,
Satellite Status Page, Navigation Page and Sonar Page) by pressing
PAGES | ← or → to select Page Name | EXIT . Switch Pages to display Satellite Status Page.
4. Wait while unit locates satellites and calculates current position. Process is visible on Satellite Page. This takes an average of 1 minute or less under clear sky conditions (unobstructed by terrain or structures.) When the unit acquires position, a tone sounds and a position acquired message appears.
5. With position acquired, press PAGES key to display Map Page, which shows a bird's eye view of the earth. You can move around the map by:
Zoom in closer to see greater detail: press ZIN (zoom in key.)
Zoom out to see more area, less detail: press ZOUT (zoom out key.)
Scroll map north, south, east or west using arrow keys ↑ ↓ → ← .
To stop scrolling and return to current position on map, press EXIT key.
6. Set a waypoint ( Wpt 001 ) at your current position so you can navigate back here: press WPT | WPT . Waypoint symbol and "001" appears.
7. Zoom/scroll map to find a nearby object or location to go to. Use arrow keys to center cursor cross-hair over the map object or location.
8. Navigate to the selected destination: press MENU | ENT | EXIT . Follow the red course line on Map Page or compass bearing arrow on Navigation Page.

Find Your Current Position
Finding your current position is as simple as turning the unit on. Under clear sky conditions, the unit automatically searches for satellites and calculates its position in approximately one minute or less.
NOTE:
"Clear sky" means open sky, unobstructed by terrain, dense foliage or structures. Clouds do not restrict GPS signal reception.
If for some reason satellite acquisition takes longer, you may be inside a structure or vehicle or in terrain that is blocking signal reception. To correct this, be sure you are positioned so that the unit's antenna module has as clear a view of the sky as possible, then turn the unit off and back on again.
Moving Around the Map: Zoom & Cursor Arrow Keys
The map is presented from a bird's eye view perspective. The current zoom range shows in the lower right corner of the screen.
1. Press the ZIN key (zoom in) to move in closer and see greater detail in a smaller geographic area.
2. Press the ZOUT key (zoom out) to move farther away and see less map detail, but a larger geographic area.
When you are traveling, the map will automatically move as you move.
This keeps your current location roughly centered on the screen.
You can manually pan or scroll the map northward, southward, eastward or westward by using the arrow keys, which launch the cross-hair map cursor. This allows you to look at map places other than your current position. To clear the cursor, press EXIT , which jumps the map back to the current position or the last known position.
Tip:
Use the cursor to determine the distance from your current position
(or last known position, when working indoors) to any map object.
Simply use the arrow keys to position the cursor over the object or landmark. The distance, measured in a straight line, appears in the pop-up box. Press EXIT to clear the cursor.

1. Use the zoom keys and the arrow keys to move around the map and find the item you wish to select.
2. Use the arrow keys and center the cursor cross-hair on the desired object. On most items, a pop-up box will give the name of the selected item.
Searching
Now that you've seen how the unit can find where you are, let's search for something somewhere else. Searching is one of the most powerful features in the Lowrance GPS product line.
In this example, we'll look for the nearest fast-food restaurant. For more information on different types of searches, refer to Sec. 9, Searching .
NOTE:
This example requires the Point of Interest (POI) database included with a high detail MapCreate 6 custom map.
After the unit has acquired a position:
1. Press WPT | ↓ to POI-R ESTAURANTS

NOTE:
Search works from mapping and POI data loaded in the LCX-104C.
If you do not have a high-detailed custom map (containing POI data) for the area you are searching loaded on the MMC, you may not find anything.
Set a Waypoint
A waypoint is simply an electronic "address," based on the latitude and longitude of a position on the earth. A waypoint represents a location, spot, or destination that can be stored in memory, then be recalled and used later on for navigation purposes.
You can create a waypoint at the cursor position on the map, or at your current position while you are navigating. You can create a waypoint at any location by manually entering the position's latitude and longitude.
You can copy waypoints from your unit to your personal computer with
MapCreate software. When you want to repeat a trip, these archived waypoints can be reloaded into your GPS unit.
To create and save a Waypoint:
These first two techniques use the Quick Save method, the fastest and easiest way to create a waypoint.
Create Waypoint at Current Position
While you are traveling, press WPT | WPT . The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 003." The waypoint symbol and number appear on the map.

WPT twice to call up Find Waypoint screen (seen in Step 2) and set a point. Step 3: a message says the waypoint has been saved. Step 4: vehicle continues on its way; number waypoint symbol is visible on map.
NOTE:
The Quick Save method uses the default waypoint symbol until you edit an existing waypoint and change its symbol. (Edit Waypoint
Symbol is described in Sec. 7.) After you have changed a waypoint symbol, the unit will remember the one you chose and use it the next time you "quick save" a waypoint. To revert back to the default symbol, edit a waypoint and choose it, or use the Reset Options command (described in Sec. 8).
Create Waypoint on Map
1. Use the arrow keys to move the cursor to the place where you want to make a waypoint.
2. Press WPT | WPT . The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 001." The waypoint symbol and number appear on the map.

Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family member fall overboard. This situation can be deadly on any body of water — fresh or salt. It's particularly dangerous at night or if you're out of sight of land. Of course, the first thing to do is remain calm and then use all standard safety procedures to rescue the person.
This unit has a man overboard feature that shows navigation data to the location where the feature was activated. To activate it, press the
ZOUT and ZIN keys at the same time. Your position at the time these keys are pressed is used as the man overboard position.
Caution:
Saving a new "Man Overboard" waypoint will overwrite and erase the previous "Man Overboard" waypoint.
Navigate Back to MOB Waypoint
Find your way back to the accident position with the Navigation Page or Map Page. When MOB is activated, the Navigation Page automatically shows the compass rose with its bearing arrow pointing toward the man overboard position, and the destination name says "Going To
Man Overboard." The Map Page displays a Man Overboard waypoint, represented by a human figure, and the steering arrow points where to steer to reach that position.

Navigate to Cursor Position on Map
The G O T O C URSOR
command navigates to the current cursor position on the map. It's a quick and handy way to navigate to anything you can see on the map display.
1. Use the cursor (controlled by the arrow keys) with the zoom in and zoom out keys to maneuver around the map until you find a location you want to go to.
2. Center the cursor over the location to select it. See the example in the following figure. (Many map items such as waypoints, Points of Interest, towns, etc. can be "selected," and appear "highlighted" with a pop-up box. Other features, such as a river or a street intersection will not appear "highlighted," but the cursor will take you to those locations just the same.)
111
Navigate to cursor. In this example, the cursor has selected the town of
Oologah, Oklahoma.
3. Press MENU | ENT and the LCX-104C will begin navigating to the cursor location.
The Map Page will display a red line from your current position to the cursor position. The Navigation Page displays a compass rose showing navigation information to your destination. See the following examples.
The 30-mile zoom figure at left clearly shows the red course line connecting your current position to your destination. The 30-mile zoom, center, shows both current position and direction to destination on screen. The
Navigation Page, right, will also show navigation information.
To stop navigating to the cursor, use the Cancel Navigation command: press MENU | MENU | ↓ to C ANCEL N AVIGATION

| ENT . The
LCX-104C stops showing navigation information.
112
Navigate to a Point of Interest
For POIs that are in view on the map, you can easily use the Navigate to Cursor command above; just use the cursor to select the POI.
The other method involves searching for POIs with the Find Waypoint command, launched with the WPT key. (See the searching example earlier in this section, or turn to Sec. 9, Searching , for detailed instructions on POI searches.)
After you have looked up an item with the Find Waypoint command, use the

Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the LCX-
104C as you travel. It's a travel history, a record of the path you have taken. Trails are useful for repeating a journey along the same track.
They are particularly handy when you are trying to retrace your trip and go back the way you came. On the screen, trails are represented by a magenta line extending from the back of the current position arrow.
The LCX-104C is set at the factory to automatically create and record a trail while the unit is turned on. The unit will continue recording the trail until the length reaches the maximum trail point setting (default is
2,000, but the unit can record trails 9,999 points long). When the point limit is reached, the LCX-104C begins recording the trail over itself.
By default, the trail flashes once a second, making it easier to see against the background map. With the default auto setting, the LCX-
104C creates a trail by placing a dot (trail point) on the screen every time you change directions. (The methods used for creating a trail and the trail update rate can both be adjusted or even turned off. See Sec. 8 for Trail Options .)
To preserve a trail from point A to point B, you must "turn off" the trail by making it inactive before heading to point C or even back to point A.
When the current trail is set inactive, the LCX-104C automatically creates and begins recording a new trail.

New trail, named "Trail 15," is created when Trail 14 is made inactive.
Any new travel will be recorded in this trail, which is active and visible. Trails do not need to be visible in order to be active.
You can save and recall up to 10 different plot trails, which can also be copied to your MMC for archiving or for transfer to your MapCreate software.

Navigating Trails
There are three methods for following a trail: visual trailing, navigating a trail (forward) and backtracking a trail (backward). Try each method to see which you prefer.
Visual trailing is the simplest method. It uses only the Map Page and requires no menu commands at all. The technique works the same if you are running a trail forward (from start to end) or backward (from end to start.) However, visual trailing provides no navigation information during the trip, such as the time to your destination.
115
The other two methods provide a full range of navigation data and work with both the Map Page and Navigation Page. The only difference between them is "navigating a trail" follows a trail forward (from start to end) while "backtracking" follows a trail in reverse (from end to start.)
When hiking at walking speed with a hand-held GPS, we often just use visual back trailing because it is a bit better at following each little turn on a foot path. At faster speeds, such as the highway or on the water, the Navigate Trail and Backtrack Trail commands are handy.
Visual Trailing
1. On the Map Page, zoom ( ZIN or ZOUT ) so your flashing trail is visible.
2. Begin moving and watch the Map Page. Simply walk or steer so that your current position arrow traces along the trail you have just made.
Tip:
Generally, when using this method, the smaller the zoom range, the more accurately you will be able to steer along the trail.

Icons
Icons are graphic symbols used to mark some location, personal point of interest or event. They can be placed on the map screen, saved and re-
123
called later for navigation purposes. These are sometimes referred to as event marker icons. The LCX-104C has 42 different symbols you can pick from when creating an icon.
Icons are similar to waypoints, but they do not store as much information (like names) as waypoints do. You can't use a menu to navigate to icons as you can with waypoints. (But, you can use the map cursor and navigate to any icon on the map.)
You can create an icon at the cursor position on the map, or at your current position while you are navigating.

Routes
A route is a series of waypoints, linked together in an ordered sequence, that's used to mark a course of travel. You can visualize a route as a string of beads: The beads represent waypoints and the string represents the course of travel connecting waypoint to waypoint.
The course from one waypoint to the next is a leg; routes are composed of one or more legs. The legs of all GPS routes are based on straight lines between waypoints.
A route provides the automatic capability to navigate through several waypoints without having to reprogram the unit after arriving at each
125
waypoint. Once programmed into the GPS unit, a route provides the option of navigating forward through the route waypoints or in reverse order (you can even begin navigating in the middle of a route!)
Create and Save a Route
You have the option of creating and editing a route in the unit, or you can make a route on your computer with our MapCreate 6 software.
PC-created Routes
MapCreate is the easiest method for preparing a route, simply because your PC's larger screen, keyboard and mouse are easier to manipulate than the gimbal-mounted LCX-104C.
To load a MapCreate route into the LCX-104C, follow instructions in
MapCreate's manual for creating a route and saving it as part of a GPS
Data File (file format *.usr). Copy the GPS Data File to an MMC and insert the MMC in the LCX-104C. (See Sec. 2 for instructions on installing MMCs. To load the GPS Data File into the LCX-104C memory, see the entry on Transfer Custom Maps & GPS Data Files in Sec. 6,
Basic GPS Operations .)
Routes Created in the Unit
You can create a route by selecting existing waypoints from the waypoint list or you can set a series of route waypoints on the map with cursor arrows and the Enter key. In this example, we'll create a route from the map.

Section 8:
System & GPS Setup Options
Alarms
This unit has several GPS alarms. The factory default setting has all the alarms turned on. You can turn the alarms off and on and change their distance settings.
You can set an arrival alarm to flash a warning message and sound a tone when you cross a preset distance from a waypoint. For example, if you have the arrival alarm set to 0.1 mile, then the alarm will flash a message when you come within 0.1 mile of the recalled waypoint.
The off course alarm warns you when your track drifts too far to the right or left of the course line to the waypoint. For example, if the alarm is set to 0.1 mile, then the alarm flashes a message if you drift
0.1 of a mile or more to the right or left of the line to the waypoint.
The anchor alarm is triggered when you drift outside of a preset radius.
Again, using the 0.1 mile as an example, if you're anchored and your boat moves more than 0.1 mile, the alarm will flash a message and sound a tone.
Alarms command, left; Alarm menu, right.
To change alarm settings:
1. Press MENU | MENU | ↓ to A LARMS

IMPORTANT ALARM NOTES:
Anchor Alarm - The anchor alarm may be triggered even when you're sitting still. This typically happens when using small (less than 0.05 mile) anchor alarm ranges.
Arrival Alarm - If you set the arrival alarm's distance to a small number and you run a route (see the Navigate Routes segment), this unit may not show navigation data to the next waypoint, once you arrive at the first one, since you may not be able to come close enough to the first waypoint to trip the arrival alarm.
Auto Satellite Search
To lock onto the satellites, the GPS receiver needs to know its current position, UTC time and date. (Elevation (altitude) is also used in the equation, but it's rarely required to determine a position.) It needs this data so that it can calculate which satellites should be in view. It then searches for only those satellites.
When your GPS receiver is turned on for the first time, it doesn't know what your position or elevation (altitude) is. It does know the current
UTC time and date since these were programmed into it at the factory and an internal clock keeps the time while the unit is turned off. (If the time and/or date are incorrect, you can set it using the "Set Local Time" menu.)
The unit begins searching for the satellites using the above data that it acquired the last time it was turned on. This probably was at the factory. Since it's almost certain that you're not at our factory, it's probably looking for the wrong satellites.
If it doesn't find the satellites it's looking for after approximately one minute, it switches to Auto Search. The receiver looks for any satellite in the sky. Due to advanced technology, the auto search time has shrunk significantly from the early days of GPS.
Once the unit locks onto the satellites, it should take less than a minute to find your position the next time it's turned on, provided you haven't moved more than approximately 100 miles from the last location it was used.

This unit can show a position in degrees (36.14952°); degrees, minutes and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan, Greek and Military grids.
UTM's are marked on USGS topographic charts. This system divides the Earth into 60 zones, each 6 degrees wide in longitude.
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan, and Greek grid systems are each the national coordinate system used only in their respective countries. In order to use these grid systems,
139
you must be in the respective country. This unit will pick the matching datum for you when you select the grid. See the entry on Map Datum
Selection for more information.
The military grid reference system (MGRS) uses two grid lettering schemes, which are referred to as standard and standard + 10 MGRS on this unit. Your position and datum in use determines which one to use. If you use standard, and your position is off significantly, then try the alternate.
NOTE: When the position format is changed, it affects the way all positions are shown on all screens. This includes waypoints.
To change the coordinate system, press ENT while C OORDINATE S YSTEM

Map Fix
Map Fix is used with charts or maps. This system asks for a reference position in latitude/longitude, which you take from a marked location on the map. It then shows the present position as distance on the map from that reference point.
140
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you then measure up four inches and to the left a half-inch from the reference point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take your map of the area and determine a reference latitude/longitude.
(Please note that in order for this system to work, the latitude/longitude lines must be parallel with the edge of the map. USGS maps are parallel, others may not be. Also, this works better with smaller scale maps.) The reference position can be anywhere on the map, but the closer it is to your location, the smaller the numbers will be that you'll have to deal with.
Once you've decided on a reference position, you can save it as a waypoint. See the waypoint section for information on saving a waypoint.
Save the reference position as a waypoint. Exit from the waypoint screens.

Map Auto Zoom
This receiver has an auto zoom feature that eliminates much of the button pushing that other brands of GPS receivers force you to make. It works in conjunction with the navigation features.
First, start navigation to a waypoint. (See the waypoint section for more information on navigating to a waypoint.) Then, with the auto zoom mode on, the unit zooms out until the entire course shows, from the present position to the destination waypoint. As you travel toward the destination, the unit automatically begins zooming in — one zoom range at a time — always keeping the destination on the screen.

Map Overlays (Range Rings; Lat/Long Grid)
The map screen can be customized with four range rings and/or grids that divide the plotter into equal segments of latitude and longitude.
Range rings are handy for visually estimating distances on the map.
The ring diameters are based on the current zoom range. For example: at the 100 mile zoom, the screen will show two rings with your current position in the center. The large ring touching the left and right sides of the screen is 100 miles in diameter (same as the zoom range). The second smaller ring is 50 miles in diameter (always 1/2 the zoom range).
The distance from your current position to the smaller ring (the ring's radius) is 25 miles (always 1/4 the zoom range). With the arrow keys and map cursor, you can scroll the map to see the third and fourth rings. In this example, the distance to the third ring is 75 miles and distance to the fourth ring is 100 miles from your current position.

Map Datum Selection
Maps and charts are based on a survey of the area that's covered by the map or chart. These surveys are called "Datums." Maps that are created using different datums will show the same latitude/longitude in slightly different locations.
All datums are named. The GPS system is based on the WGS-84 datum, which covers the entire world. Other datums may also cover the entire world, or just a small portion of it. By default, your position shows using the WGS-84 datum. However, it can show your position using one of 191 different datums. Different datums can be selected; to change the datum:
1. Press MENU | MENU |

Map Orientation
By default, this receiver shows the map with north always at the top of the screen. This is the way most maps and charts are printed on paper.
In Track Up mode, map shows "N" and arrow to indicate north.
Map orientation at left is shown in north up and at right, track up.
This is fine if you're always traveling due north. What you see to your left corresponds to the left side of the map, to your right is shown on the right side of the map, and so on. However, if you travel any other direction, the map doesn't line up with your view of the world.
To correct this problem, a track-up mode rotates the map as you turn.
Thus, what you see on the left side of the screen should always be to your left, and so on.
Another option is course-up mode, which keeps the map at the same orientation as the initial bearing to the waypoint. When either the track-up or course-up mode is on, an "N" shows on the map screen to help you see which direction is north.

Position Pinning
When you are standing still or moving at extremely slow speed, a GPS receiver can have trouble determining the direction you are traveling.
In the past, this resulted in a "wandering" plot trail that moved around the map, even if you were standing still.
The Position Pinning feature was developed so that when you stopped, the unit locked the present position on the GPS plotter until you moved a short distance or exceeded a very slow speed.
The command remains available in the unit's software, but we recommend that you leave it in the default off (unchecked) mode. The "wandering" plot trail issue has now been corrected by the Track Smoothing feature. Turning on Position Pinning could actually result in an inaccurate plot trail if you are moving around in a relatively small area. If you want to experiment with Position Pinning, the same instructions are used to turn the feature on (checked) and off (unchecked.)

Show WAAS Alarm
When the signal is available, your unit will automatically use WAAS to boost the accuracy of the position fix. When the WAAS signal is lost or acquired, an alarm message appears. Since the U.S. government is still developing the WAAS system, it's not unusual for a GPS/WAAS receiver to frequently lose and reacquire its lock on a WAAS satellite.
That can result in the alarm repeatedly going on and off. If you want, you have the option of turning off the WAAS Acquired/Lost alarm without affecting how the unit uses WAAS. Here's how:

Once you deviate from a straight line, the unit "drops" a plot point (trail waypoint) onto the trail. This conserves plot trail points. If a plot trail uses all of the available points allotted to it, the beginning points are taken away and placed at the end of the trail.

ANY CIRCUMSTANCES BE LIABLE TO ANYONE FOR ANY SPECIAL,
CONSEQUENTIAL, INCIDENTAL, OR OTHER INDIRECT DAMAGE OF
ANY KIND.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you.
This warranty does NOT apply in the following circumstances: (1) when the product has been serviced or repaired by anyone other than us; (2) when the product has been connected, installed, combined, altered, adjusted, or handled in a manner other than according to the instructions furnished with the product; (3) when any serial number has been effaced, altered, or removed; or
(4) when any defect, problem, loss, or damage has resulted from any accident, misuse, negligence, or carelessness, or from any failure to provide reasonable and necessary maintenance in accordance with the instructions of the owner’s manual for the product.
We reserve the right to make changes or improvements in our products from time to time without incurring the obligation to install such improvements or changes on equipment or items previously manufactured.
This warranty gives you specific legal rights and you may also have other rights which may vary from state to state.
Your remedies under this warranty will be available so long as you can show in a reasonable manner that the defect occurred within one (1) year from the date of your original purchase, and we must receive your warranty claim no later than 30 days after such 1-year period expires. Your claim must be substantiated by a dated sales receipt or sales slip.
