EMC Installation & Service Guidelines
IMPORTANT NOTE
All JRC equipment and accessories are designed to the highest industry standards for use in a marine environment. Their design and manufacture conforms to the appropriate Electro Magnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised.
Although every effort has been taken to ensure that the equipment will perform under all conditions, it is important to understand what factors could affect operation of the product. Complete installation instructions are provided in
SECTION 3 of this manual. Some preliminary suggestions are made below.
Installation
To avoid the risk of operating problems, all JRC equipment and cables connected to it should be:
• At least 1m (3 feet) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios the distance should be increased to 2m (7 ft).
• More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally assume to spread 20 degrees above and below the radiating element.
• The equipment should be supplied from a different battery than the one used for engine start. Voltage drops below 10V in the power supply to our products can cause the equipment to reset. This will not damage the equipment, but will cause some loss of information and this can also change the operating mode.
• Genuine JRC Cables should be used at all times. Cutting and rejoining these cables can compromise EMC performance and should therefore be avoided unless doing so is suggested in the installation manual.
Check Before Going to Sea
• Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting, low battery voltage, or other problems.
• In some, installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to it resetting, or momentarily may result in faulty operation. This can then be avoided by turning off the FF50 prior to starting the boat engines for instance.
5
Servicing and Safety
• JRC equipment should be serviced only by authorized JRC service engineers.
They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any JRC product .
• Some products generate high voltages, and so never handle the cables /connectors when power is being supplied to the equipment.
• Always report any EMC related problem to your nearest JRC dealer. We will use any such information to improve our quality standards.
Suppression Ferrites
The following illustration shows the range of suppression ferrites fitted to
JRC equipment.

Notes for Suppression Ferrite Installation
Connections to other equipment
If your JRC equipment is going to be connected to other equipment using a cable not supplied by JRC, a suppression ferrite MUST always be fitted to the cable close to the JRC unit.

SECTION 1
Introduction
Function
The Color Fish Finder FF50 is a system that uses the basic principles of sonar to show lake or seabed conditions and to detect fish. It consists of a transducer, which is installed on the transom, or thru-hull transducer, and a display unit.
The transducer and the display unit are connected by a 25- feet transducer cable.
The transducer sends ultrasonic signals down into the water and receives back echoes. The echoes appear to form images on the display unit.
System Components
The Color Fish Finder FF50 consists of a compact display unit connected to a transducer mounted on the boat, or optionally through the hull.
Use of the GPS capabilities requires the optional GPS 100: JRC’s GPS sensor.
Use of the DGPS capabilities requires the optional DGPS200: JRC’s DGPS sensor.

Features
DUAL FREQUENCY
Because two frequencies, 200 kHz and 50 kHz can be used, the areas used to search for schools of fish is more flexible and information on the type of fish or seabed can be better determined by comparing echoes of each frequency.
The display in the dual-frequency mixed mode is also available. In this mode, the difference of the echoes between two frequencies is clear.
Simple Navigation Aids Feature
By connecting an optional GPS or DGPS sensor, such information as the position or course of your ship can be displayed on the screen.
By registering WAYPOINT and ROUTE PLAN, it is also possible to display such important information as the distance or bearing to/of a WAYPOINT that ensures safe and economical navigation.
This information can be displayed in the intuitive illustration style or in the numerical style depending on your selection.
Auto Control Feature
Four Auto Control features are selectable depending on various circumstances,
So anyone unfamiliar with this equipment can use these Auto Control Settings easily.
Various Alarms Feature
There are several Alarms such as FISH Alarm, SHALLOW/DEEP Alarms,
TEMP UPPER/LOWER Alarms, and each Alarm calls your attention to the situation by making the buzzer sound.
Note
An optional GPS/DGPS sensor is required to use Alarms relating to the navigation information.
Water Temperature and Vessel Speed Measuring Feature
The water temperature/vessel speed sensor is integrated in the transducer so that the water temperature and vessel speed can be measured without any Additional connections.
Easy-to-operate
It is very easy to operate various features just by using the joy stick and the jog dial.

Installing the Transducer
About the Transducer
The transducer sends ultrasonic signals down into the water. The signals travel down until they hit an object or the seabed and then return to the transducer. The unit measures the time it takes the signals to go down and return to the transducer, then converts the data into electronic signals, which are then converted to images on your display. The echoes form an image indicating your depth, fish, and the contour and condition (hard, soft etc.) of the seabed.
The transducer is the heart of the FF50 operation. It is a delicate instrument and should be handled carefully. The position that you mount the transducer is extremely important and this directly affects the performance and operating efficiency of the unit. Please read this section carefully and follow these instructions when you install the transducer.

Adjusting
➀
Using a straight edge, sight the underside of the sensor relative to the underside of the hull. The stern of the sensor should be 1/16-1/8" (1-3mm) below the bow of the sensor or parallel to the bottom of the hull (see Figure
3-7).
CAUTION
Do not position the bow of the sensor lower than the stern because aeration will occur.
➁
To adjust the sensor’s angle relative to the hull, use the tapered plastic shim provided. If the bracket has been temporarily fastened to the transom, remove it. Key the shim in place on the back of the bracket.
2°-10° transom angle
(stepped transom and jet boats) - Position the shim with the tapered end down.
19°-22° transom angle
(small aluminum and fiberglass boats) - Position the shim with the tapered end up.
➂
If the bracket has been temporarily fastened to the transom, remove it. Apply a marine sealant to the threads of the two #10 x 1-1/4" self-tapping screws to prevent water seeping into the transom. Screw the bracket to the hull. Do not tighten the screws completely at this time.
➃
Repeat step 1 to ensure that the angle of the sensor is correct.
CAUTION
Do not position the sensor farther into the water than necessary to avoid increasing drag, spray, and water noise and reducing boat speed.
➄
Using the vertical adjustment space on the bracket slots, slide the sensor up or down to provide a projection of 1/8" (3mm). Tighten the screws (see
Figure 3-9).

If the retaining cover near the top of the bracket is closed, open it by depressing the latch and rotating the cover downward (see Figure 3-8).
➁
Insert the sensor’s pivot arms into the slots near the top of the bracket.
➂
Maintain pressure until the pivot arms click into place.
➃
Rotate the sensor downward until the bottom snaps into the bracket.
➄
Close the retaining cover to prevent the accidental release of the sensor when the boat is underway.

Cable Routing
Route the sensor cable over the transom, through a drain hole, or through a new hole drilled in the transom adove the waterline.
CAUTION
Never cut the cable or remove the connector; this will void the warranty.
WARNING
Always wear safety goggles and a dust mask.
➀
If a hole mast be drilled, choose a location well adove the waterline. Check for obstructions such as trim tabs, pumps, or wiring inside the hull. Mark the location with a pencil. Drill a hole through the transom using a 19mm or
3/4" bit (to accommodate the connector).
➁
Route the cable over or through the transom.
➂
On the outside of the hull secure the cable against the transom using the cable clamps. Position a cable clamp 2" (50mm) adove the bracket and mark the mounting hole with a pencil (see Figure 3-9).
➃
Position the second cable clamp halfway between the first clamp and the cable hole. Mark this mounting hole.
➄
If a hole has been drilled in the transom, open the appropriate slot in the transom cable cover. Position the cover over the cable where it enters the hull.
Mark the two mounting holes.
➅
At each of the marked locations, use a 3mm or 1/8" bit to drill a hole 3/8"
(10mm) deep. To prevent drilling too deeply, wrap masking tape around the bit 3/8" (10mm) from the point.
➆
Apply marine sealant to the threads of the #6 x 1/2" self-tapping screws to prevent water from seeping into the transom. If you have drilled a hole through the transom, apply marine sealant to the space around the cable where it passes through the transom.
➇
Position the two cable clamps and fasten them in place. If used, push the cable cover over the cable and screw it in place.
➈
Route the cable to the instrument being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the sensor cable from other electrical wiring and “noise” sources. Coil any excess cable and secure it in place with zip-ties to prevent damage.
➉
Refer to your echosounder owner’s manual to connect the sensor to the instrument.

Testing on the Water
➀
Become familiar with your echosounder’s performance at a speed of 4kn
(5MPH).
➁
Gradually increase the boat speed and observe the gradual decline in performance due to turbulent water flowing over the transducer’s active surface.
➂
If the degradation is sudden (not gradual), identify the boat speed at which the onset occurred. Return the boat to this speed, then gradually increase speed while making moderate turns in both directions.
➃
If the performance improves while turuing, the sensor’s position probably needs adjustment, because it is in aerated water. Move the sensor farther down into the water in increments of 1/8" (3mm). If the performance does not improve satisfactorily, move the sensor closer to the centerline of the boat. Fill unused screw holes with marine sealant.
High speed operation
- May require less projection in the water.
Checking for Leaks
WARNING
When the boat is placed in the water, immediately check for leaks around the screws and any holes drilled in the hull. Never install a sensor and leave the boat in the water unchecked for several days.
Antifouling Paint
Marine growth can accumulate rapidly on the sensor’s surface reducing performance in weeks. Surfaces exposed to salt water that do not interlock, must be coated with antifouling paint. Use water-based antifouling paint only. Never use ketone-based paint, since ketones can attack many types of plastic possibly causing damage to the transducer. Apply paint every 6 months or at the beginning of each boating season.
33
34
Maintenance
Cleaning
Clean the sensor with a soft cloth and mild household detergent. If fouling occurs, use a stiff brush or putty knife to remove the growth being careful to avoid making scratches on the transducer’s face. In severe cases, wet sand the surface with fine grade wet/dry paper.
If the paddlewheel becomes fouled or inoperable, it can be removed for cleaning. Remove the two screws from the paddlewheel assembly. Lift the assembly to remove it from the transducer. Grasp the two retaining bars and pull to access the shaft.
After cleaning, slide the paddlewheel onto the shaft and fit the shaft into the two retaining bars. Slide the assembly into the paddlewheel housing being sure the flat side of the paddlewheel blade matches the side view below. Screw the assembly in place (see Figure 3-10).

Using a Thru-Hull Transducer
In place of the standard transom mount transducer you can also install a thru-hull transducer as shown in Figure 3-11. Please read this section completely before starting installation.
Normally, this type of installation is performed by a professional. You may want to seek some local assistance before attempting to mount this type of transducer.

Before You Install
➔
Do not install a bronze transducer housing directly into an aluminum or steel hull due to electrolytic corrosion.
➔
Do not install the thru-hull then leave your boat in the water for any amount of time without checking for leaks.
➔
Top speed capability is critical in positioning the transducer. For power boats capable of more than 20 knots, check location and operational results on similar boats before installing.
➔
Follow appropriate procedures for thru-hull mounting in core hull structures.
If you are in any doubt about installation, consult your boat representative, or
JRC dealer.
Selecting the Best Location
If properly installed the thru-hull transducer will be:
• where bubbles will not pass over the transducer face (especially at higher speeds).
Watch for bubbles caused by shaft struts, fittings, and other paddle wheel speed transducers. Paint erosion on the hull is a sign of turbulence.
• continuously immersed in water. Mount well aft and close to the keel on high speed power boats. Mount amidships and relatively close to the hull centerline on displacement hulls. Mount forward of the fin keel on sailboats.
• where you can easily access the transducer from inside the vessel for adjustments and periodic inspections-a minimum of 6" (152 mm) of headroom above the transducer.
• where the transducer beam is not obstructed by keels or prop shafts.
35

Figure 3-12 shows best location for the thru-hull transducer.
Best locations vary with the type of vessel. On any vessel, try to find a spot with the smallest deadrise angle.

Using a Fairing Block
If necessary, use a fairing block as shown in Figure 3-13 to keep the transducer perpendicular to the waterline, especially if the deadrise angle at the mounting point exceeds 10 degrees.
Fairing blocks are usually constructed of wood (such as mahogany) and shaped to both reduce drag and minimize aeration on the transducer face. Best results are obtained with sharp vertical leading edge fairings because this wedge shape helps divert aerated water off to the sides of the transducer away from the acoustic face.

Installing the Thru-Hull Transducer
You may wish to drill a 1/8" (3.2 mm) pilot hole from the inside to assure access to the housing nut and clearance for the cable. Drill from the outside if there is a strake or other hull irregularity.
Use caution when sanding or cleaning as harsh cleaning solvents such as acetone weaken some epoxy resins and may damage the transducer.
Normally, this type of installation is performed by a professional. You may want to seek some local assistance before attempting to mount this type of transducer.
➀
Drill the hole from the outside using a 2" (50.8 mm) hole saw or paddle bit.
➁
Remove the hex nut from the housing and cable.
➂
Uncoil the transducer cable and thread through the hole to the inside of the hull. NEVER pull or carry the sensor by the transducer cable, as you may sever internal connections. NEVER hold the transducer in place by pulling on the transducer cable.
➃
Apply a 1/8" (3.2 mm) thick layer of sealant on the transducer between the upper flat surface of the transducer and fairing block, following the manufacturer’s directions. Apply a thin layer up the side walls, 1/4" (6 mm) higher than the hull and shim thickness, to seal the threads securing the housing nut.
➄
Push the sensor housing (with sealant applied) into the drilled hole from the outside of the hull. Twist the housing slightly to squeeze out excess sealant.
Confirm that the transducer is aligned so that the wedge portion is toward the bow of the vessel.
➅
Tighten the hex nut (allow for swelling in wooden hulls).
➆
Remove excess sealant from the outside to assure smooth water flow over the transducer.
➇
Check for leaks as soon as the boat is placed in the water, and AGAIN within
3 to 5 hours (small leaks may not be readily observed). Seal any leaks by repeating the installation procedure.

Connecting DC Power
WARNING
Do not touch the ground terminal and vessel ground on the display unit at the same time without the ground terminal earthed. Otherwise, you may suffer an electric shock.
CAUTION
RED to the positive.
BLACK to the negative.
Do not mistake the colors, as doing so will cause a malfunction.
Your unit is intended for use on vessels with 12 or 24 VDC power systems and it can operate as long as the DC supply is maintained between 11 and 32
VDC.
The supplied 5 foot power cable assembly should reach the source of DC power.
➔
On larger boats, route the power leads to the ship’s DC power distribution panel. Connect to 3 amp or 5 amp (maximum) circuit breaker, as the unit is fused at 3 amps.
➔
On smaller vessels connect the power leads directly to the main battery isolation switch or breaker.
Avoid grouping the unit’s power connections with radar, radio, or Loran-C power leads on the same circuit breaker. Separate the wiring as much as possible from other devices to prevent electrical noise interference.
Although the unit’s power consumption is approx. 25 watts, if you need to extend the power cable leads by more than 10 feet, increase the wire size of the leads accordingly to minimize line losses. For runs of 20-35 feet, #12 AWG is recommended.
➔
Connect the RED wire to the positive (+) source terminal as shown in Figure
3-14.
➔
Connect the BLACK wire to the negative (-) source terminal as shown in
Figure 3-14.
If the power leads are accidentally reversed, the in-line fuse will blow. If this happens, recheck the polarity of the connections with a volt-meter (VOM) and, if necessary, reverse the leads for proper connection.
Then, replace the fuse.
If the unit will not turn on and you suspect that you may have reversed the power connections, check the DC power lines all the way back to the battery. If the polarity is not correct, properly reconnect the leads and try again.
The unit is internally protected from accidental reverse polarity.
Reversing the power leads will not damage the unit, it will simply not turn on.

Ship's Ground
System
Figure 3-14
Grounding the Display Unit
One very important requirement in installation of shipboard electronics is to obtain the cleanest, noise-free environment possible so each piece of electronic equipment can work to its best performance levels. This requirement is accomplished by assuring a proper connection from each equipment to the ship’s
RF ground system. The ground provides a drain for shipboard noise transmission and pickup.
A separate ground wire of # 10 or # 12 AWG (# 10 recommended) should be connected from the ground terminal on the rear of the unit to the nearest connection point of the ship’s ground system.
Normally, on a steel hull boat, a good clean connection to the hull provides a sufficient ground. On a fiberglass or wood hull, connection to a ground plate or to the engine block and other bonded groundwork should be acceptable.

Connecting GPS/DGPS Sensor or Making
NMEA0183 Data Connections (Option)
When displaying the latitude and longitude of your vessel on the screen, or using the NAVIGATION mode, you are required to connect the optional
GPS100 or DGPS200 sensor to the FF50, or input the data of navigational information in the NMEA0183 format from navigation equipment.
Connecting GPS100 or DGPS200 sensor
When using the GPS100 or DGPS200 sensor, connect the 5-pin antenna connector attached to the signal cable of the sensor to the “GPS” connector at the rear panel of the unit.
With this, it is possible to receive the necessary data of navigational information from the GPS100 or DGPS 200 sensor. It s advisable, however, to perform initial settings according to your conditions using the INSTALLATION menu of the unit for more precise navigational information. Refer to “Installation
Menu” p.71 for the information about initial settings for each sensor.
Making NMEA0183 data connections
When receiving navigational data information in the NMEA0183 format from navigation equipment other than this unit, you are required to make a connecting cable using the 5-pin connector (model 6-282-5SG-325, CONXALL) and connect it to the “NMEA” connector at the rear panel of the unit.
Connect the 5-pin connector and the connecting cable as shown in Fig. 3-15.

to close the menu and enter the selected
The FF50 provides 11 display modes. You can obtain the optimum display according to various purposes such as game fishing or normal navigation.
The displays of each mode are described below.
STD Single Frequency Mode
• Select STD to display the standard full screen display for high or low frequency. The operating status such as gain, noise suppression and interference rejection are indicated. Numerical data such as water depth, water temperature, vessel speed, your vessel position, the depth scale, and the variable range marker (VRM) are displayed on the screen also.
This data is common to each display mode.
Push to toggle between the high and low frequencies.
51
52
STD Dual Frequency Mode
• Select STD DUAL to divide the screen vertically in two in the ratio of
1:1. It shows the high frequency standard display on the right side of the screen and the low frequency standard display on the left side of the screen. In this mode, it is easy for the operator to recognize the fish type because the echoes of schools of fish differ distinctly between high and low frequencies.
STD Single Frequency with A-Scope Mode
• Select STD/A-SCOPE to divide the screen vertically in two in the ratio of 6:1. It shows the A-Scope, corresponding to the standard display on the right side of the screen, and the low or high frequency standard display on the left side of the screen. The A-Scope shows the amplitude of the fish and bottom echoes through the color and width of each echo transmission. Greater width, and higher color level (the maximum level is 15) indicate, stronger signals. This makes it easier for the operator to recognize a big fish instantaneously because the amplitude of the echo from a big fish is large even though the echo itself is not so strong.
Push to toggle between the high and low frequencies.
STD Dual Frequency with A-Scope Mode
• Select DUAL/A-SCOPE to divide the screen vertically in four in the ratio of 3:1:3:1. It shows the high frequency standard display with the corresponding A-Scope on the right side of the screen and the low frequency standard display with the corresponding A-Scope on the left side of the screen.
STD Single Frequency with VRM Zoom Mode
• Select STD/ZOOM to divide the screen vertically in two in the ratio of 1:1. It shows the high or low frequency standard display on the right side of the screen and the magnified display of the area specified in the ZOOM RANGE setting, with VRM being in the center of the standard display on the left side of the screen. In this mode, it is possible for the operator to magnify any area in the STD range by moving the VRM up or down. It is recommended to use this mode when you look for schools of fish in mid-depths.
Push to toggle between the high and low frequencies.
STD Single Frequency with Auto Zoom Mode
• Select STD/AUTO ZOOM to divide the screen vertically in two in the ratio of 1:1. It shows the high or low frequency standard display on the right side of the screen, and the magnified standard display of the area near the sea bottom on the left side of the screen. In this mode, the magnified area shifts automatically so that the echoes of the sea bottom are displayed in the magnified area on the screen. This mode is recommended when you want to see a magnified display of the sea bottom contours.
Push to toggle between the high and low frequencies.
STD Single Frequency with Bottom Zoom
Mode
• Select STD/BTM to divide the screen vertically in two in the ratio of
1:1. It shows the high or low frequency standard display on the right side of the screen and the magnified standard display of the area just above the sea bottom on the left side of the screen. In this mode, the sea bottom is displayed with lines. This mode is recommended when you want to look for schools of fish near the sea bottom or when measuring the height of fish-breeding reefs.
Push to toggle between the high and low frequencies.
53
54
STD Single Frequency with Bottom
Discrimination Mode
• Select STD/BTM DISCRIM to divide the screen vertically in two in the ratio of 1:1. It shows the high or low frequency standard display on the right side of the screen. The magnified display of the area just above the seabed shows on the top half of the left side. The bottom half of the left side shows the standard display of the sea bottom, with the sea bottom surface in the center. In this mode, the bottom line is displayed with respect to the sea surface as a reference. Therefore, it is easy to check the bottom line. In general, a narrow bottom line indicates that the seabed is hard and a thick bottom line indicates a soft seabed. This mode is recommended when you want to roughly determine seabed conditions such as rock, sand or mud.
Push to toggle between the high and low frequencies.
Dual Frequency Mixed Mode
• Select STD/MIX to divide the screen vertically in two in the ratio of
1:1. It shows the high frequency preferred or low frequency preferred mixed display on the right side of the screen and the standard display of the frequency other than that used for the mixed display on the left side of the screen. In the preferred mixed display, echoes of only one of the frequencies are displayed in the normal color and echoes of both frequencies are displayed in the color of the maximum level. The strength of echoes of fish differ depending on the frequencies. In other words, echoes of schools of fish are displayed differently for each frequency. For example, the echoes of small marine life, such as shrimp, may be obscure in the low frequency, but echoes of a large fish such as tuna are clearly visible in both high and low frequencies.
Therefore, the echoes displayed in the normal color on the high frequency preferred mixed display may be regarded as small fish. On the other hand, the beam of the Transducer connected to the FF50 is narrow in the high frequency and wide in the low frequency. Echoes of schools of fish near the vertical line from the Transducer may be displayed in both high and low frequencies, and echoes of schools of fish away from the line are probably displayed only in the low frequency. Therefore echoes displayed in the normal color on the low frequency preferred mixed display can be regarded as those of fish away from your vessel.
Push to toggle between the high and low frequencies.
Navigation Mode type1 (Graphic Display)
• Select STD/NAV1 to divide the screen vertically in two in the ratio of
6:1. It shows the high or low frequency standard display on the right side of the screen and the NAVIGATION type1 window on the left side of the screen.
The NAVIGATION type1 window includes the numerical data, compass window and highway window. Three types of information are displayed at the same time. The numerical data includes such information as water depth, vessel speed, course, and your vessel’s position. The compass window indicates the relation between your vessel’s course and the destination. The highway window indicates your vessel’s position relative to the course. The water temperature and
Trip Log are also displayed at the top of the screen. To display the information mentioned above, however, it is necessary to connect a
GPS/DGPS sensor (optional) and activate FOLLOW ROUTE, or to receive the NMEA0183 formatted navigation information sentences from external navigation aids and switch the NAVIGATION function from internal monitor to external monitor. Refer to “Monitor Mode” p.70 for information about how to switch to the external monitor.
Push to toggle between the high and low frequencies.
Note:
The Trip Log is calculated from the indicated vessel speed. For this reason, when through water is selected, a value different from the true distance traveled may be displayed due to the influence of current and other factors.
Navigation Mode type2 (Numeric Display)
• Select STD/NAV2 to divide the screen vertically in two in the ratio of
6:1. It shows the high or low frequency standard display on the right side of the screen and the NAVIGATION type2 window on the left side of the screen.
The NAVIGATION type2 window includes the numerical data of various navigation information such as water depth, vessel speed, course, heading direction, waypoint direction, distance between your vessel and the waypoint, deviation from the course, your vessel’s position, etc. The water temperature and Trip Log are also displayed at the top of the screen. To display the information mentioned above, however, it is necessary to connect a GPS/DGPS sensor (optional) and activate FOLLOW ROUTE, or to receive the NMEA0183 formatted navigation information sentences from external navigation aids and switch the NAVIGATION function from internal monitor to external monitor. Refer to “Monitor Mode” p.70 for information about how to switch to the external monitor.
Push to toggle between the high and low frequencies.

SECTION 5
Maintenance
WARNING
Do not try to service the interior of the unit, except by qualified service personnel, as doing so may cause an electric shock or functioning error.
Call our company, branch, local office, or authorized agent for maintenance and inspection of this unit.
Note
Before you go any further, please take a few minutes to fill out the warranty card and send it in at your earliest convenience. It is very important that you return the warranty registration card to the factory directly after your purchase to insure full warranty benefits.
If you keep your transducer in salt water, you will need to protect it with anti-fouling paint. Sea growth on the transducer face can accumulate rapidly and seriously reduce the performance in a matter of weeks. For easier maintenance, coat the bottom. Use only mineral spirits-based anti-fouling or transducer paint and apply with a brush.
If your transducer becomes fouled or inoperable because of sand or debris, use a stiff brush or putty knife to remove it. Wet sanding with a #320 grade or finer wet or dry paper is permissible, but will compromise high speed performance slightly.
You can maintain satisfactory operation of your unit depending on how well you care for the equipment. The simple maintenance tips that follow can save you time and money, as well as prevent unnecessary, premature failures.
➔
Always keep the equipment as clean as possible.
Use a soft clean cloth for cleaning the surface filter, control panel, etc. Do not use abrasive cleansers, chemical cleaners or solvents unless specifically recommended by this manual. Use glass cleaners or a suitable general purpose detergent.
➔
Periodically check system hardware.
Inspect the transducer and mounts making sure all components are free of corrosion and are securely mounted. Examine all cables for evidence of chafing or abrasions. Make sure connections to the vessel’s DC power and
RF ground system are clean and tight.
SECTION 6
Principal
Sonar Basics
A Fish Finder is a device which transmits ultrasonic signals into the water and listens for echoes. The signals travel down until they hit an object or the seabed and then return to the transducer. The resultant echo appears on your display.
The time taken for the signals to bounce off submerged objects or the seabed, and return as echoes is measured. The data is then converted into units of depth and can be shown in many ways such as on an LCD panel or CRT display.
The frequency of the wave or pulse, the transmitting angle of the beam, and the power of the pulse itself, all play important parts in determining the appearance of the echo traces on the display.
The seabed, schools of fish, seaweed, grass, bubbles, plankton, etc. all send echoes of different strengths. Generally, the seabed sends the strongest echo, while other objects send relatively weaker echoes.
The Fish Finder is able to distinguish fish from seaweed, grass etc. because the air bladder of the fish is the object with the most density.
Echo Sounding
As the boat travels, echoes returning to the transducer are received which continuously update the FF50 display.
Receiving and identifying echoes from fish can depend on several factors including:
•Species of fish
•Number and size of fish
•Fish depth below the boat
•Sensitivity level
•Power and frequency of the sounder
•Transducer beam angle
•Boat speed
•Water turbulence

Seabed Conditions
After some experience, you will begin to understand and recognize different seabed conditions (sand, mud, rocks, etc.), by paying attention to variations in the sea bottom return being drawn on the display. When water depth and sensitivity settings remain the same, the display may show variations in the sea bottom return image caused by changing bottom conditions.
Echoes appear at the right edge, adjacent to the range scale, and scroll left across your display. Each time the Fish Finder transmits and receives, old echoes shift to the left to make room for the new echoes. As your vessel moves, an image of the bottom contour and fish echoes that you pass fill your display.
• When the seabed is hard and flat like a mirror, only the beam directly under the transducer is reflected back to the transducer. This echo appears on your display as a narrow bottom line, characteristic of hard, sandy seabeds.
• When the depth is shallow and the seabed very hard, a second echo can appear at exactly double the depth of the true seabed echo.
• When the seabed is soft (an abundance of seaweed or mud), the bottom line on your display appears thicker. This is because the top surface of the sea weed or mud sends a weaker echo than the bottom itself and also because waves returning to the transducer may be slightly delayed.
• When the seabed is made up of coral, wrecks, or rock piles, the irregular surfaces and various angles of the seabed return closely spaced echoes. The bottom line on your display appears with irregular long tails.

GPS/DGPS Basics
GPS
The Navstar/GPS system is a satellite-based radio navigation system designed to provide global, continuous 24 hour-per-day, all weather, accurate position data for navigators. The GPS(Global Positioning System) is based on a GPS sensor’s ability to accurately measure the propagation time of signals transmitted from orbiting satellites in your sensor.
The satellites transmit accurately timed signals along with a navigation message which includes the satellite’s position (orbit or ephemeris data), precise time (clock) correction signals, and almanac data for the complete constellation of satellites.
GPS System
Figure 6-3
The complete constellation will consist of 24 satellites (3 spare satellites) in 6 orbital planes. Four satellites are equally spaced in each plane.
The four satellites equally spaced in each plane circle the globe once every 12 hours at a distance of approximately 20,000Km from the Earth.
The satellites continuously broadcast their navigation messages at a frequency of 1575.42MHz (for civilian use). The message is repeated every 30 seconds.
Superimposed on the navigation message is a high rate C/A (coarse/acquisition) code used for precise positioning measurements and positive satellite identification. The C/A ID code permits the user to determine and select the
“best satellites” to use in position calculations.
If it were possible to measure “true satellite ranges” directly, it would only be necessary to track data from any two satellites to obtain a vessel’s latitude/ longitude. In actual practice, for marine navigation, a minimum of three satellites are normally tracked in order to reduce the sensor’s own internal clock timing bias error.
By calculating the ranges of four satellites, the clock timing bias error can be eliminated and the vessel’s three dimensional position can be determined.
91
92
Differential GPS (DGPS)
The differential GPS comprises a reference station with its position(latitude and longitude) accurately known, a beacon station for radio broadcasting of
DGPS correction data, and user-owned GPS sensor equipped with a differential correcting function.
The GPS sensor is used to fix the position of the reference station whose position is accurately known and to eompare this with the actual reference station position to get range errors. The range errors are transmitted to the beacon station as the DGPS correction data and are broadcast from the beacon station to the user. This DGPS correction data is received by the user-owned beacon receiver, and is sent to the GPS sensor. The GPS sensor calculates its own position by adding the correction data to the actual data transmitted from the satellites.
Compared with the fixed positioning provided by existing GPS sensors, the
DGPS system calculates the position with a very small error not exceeding 10%.
