There will be many times that you may need to enter data. An example is
naming a waypoint. The ROCKER Key is used to navigate through menu items
and to enter data.
Getting Started
Let’s combine a couple of lessons. We will create a new waypoint, enter a
waypoint name, and assign a symbol to the waypoint.
Entering Data
Symbol Field
The term ‘Waypoint’ may be new to you. You will find the term Waypoint
is used frequently when talking about navigation. A Waypoint is a position
stored in the unit’s memory. Waypoints are used for direct navigation or to build
a Route.
Name Field
Creating or ‘Marking’ a waypoint with the GPSMAP 76 is easy. The unit has
to be turned on and receiving at least three satellites (or simulating navigation)
to mark a waypoint.
Marking a waypoint:
1. Press and hold the ENTER Key.
When you held the ENTER Key the GPSMAP 76 captured it’s current position, and displayed the Mark Waypoint Page. You will notice that the unit
assigned a square as the default symbol and a number as the default name. The
‘OK’ Button is highlighted, pressing the ENTER Key will store the new waypoint
using the default settings for the symbol and name, but let’s change them to
something more meaningful.
Mark Waypoint Page
Changing the symbol:
1. Using the ROCKER Key, highlight the Symbol Field, then press ENTER.
2. Using the ROCKER Key, highlight the ‘Scenic Area’ symbol, then press ENTER.

03/15/01, 9:24 AM
Changing the name:
1. Press the ROCKER Key right to highlight the Name Field then press the
ENTER Key.
The Name Field will become active and the first zero will be highlighted.
Notice that there are now ten placeholders for alpha-numeric characters displayed.
Getting Started
1. Press the ROCKER Key to the left to clear the field.
Entering Data
2. Press the ROCKER Key up, scroll through the alpha-numeric list until the
letter ‘C’ is selected.
3. Press the ROCKER Key right to move to the next placeholder.
4. Press the ROCKER Key down, scroll through the alpha-numeric list until the
letter ‘R’ is selected.
You should be starting to get the feel of it. Continue entering letters until you
have spelled the word CREEK.
5. With the letter ‘K’ highlighted, press the ENTER Key to accept the name.
When you have finished renaming the waypoint you will need to store it in
the units’ memory.
Entering a name
To store the waypoint:
1. Using the ROCKER Key, highlight the ‘OK’ Button and press the ENTER Key.
UP
These are the same steps that you will use to enter names and change numbers
and select options in all of the fields in the GPSMAP 76.
LEFT
Here are a couple of tips:
RIGHT
1. If you press and hold the ROCKER Key while scrolling through the alphanumeric list, it will move quickly.
2. You can scroll through the alpha-numeric list in either direction.
3. Don’t press the ENTER Key until you have finished entering the data.

You should now have enough knowledge to navigate through the main pages,
Option Menus and enter data into your GPSMAP 76. Now let’s learn how to
navigate!
Getting Started
Basic Navigation
The main use of a GPS is to be able to navigate to a known position. We have
already created a waypoint and named it CREEK. Let’s create another waypoint
on the Map Page using a different method, the Map Pointer.
Bearing and Distance from Pointer
to current GPS location.
Press the PAGE Key until the Map Page is displayed. Press the IN Key several
times until the Zoom Scale in the lower left corner of the Map Page reads 800ft.
The current GPS location is indicated by the triangle in the center of the map.
To display the Map Pointer:
1. Press the ROCKER Key any direction.
Using the ROCKER Key you can pan the Map Pointer around the map. As
you move around the map, the direction and distance from the Map Pointer to the
current GPS location is displayed along the top of the map.
To mark a waypoint using the Map Pointer:
1. With the Map Pointer at a location on the map about one mile from your
current location, and not on a road or map feature, press the ENTER Key.
The location of the Map Pointer will be captured and the New Waypoint Page
will be displayed. Change the waypoint name to MAP 1, and store the waypoint
in memory by highlighting the ‘OK’ Button then pressing the ENTER Key. Press
the QUIT Key to hide the Map Pointer and center the map on the current GPS
location.
Now that we have a destination, navigating to it is just a step away.
Map Pointer
16
190-00230-00.indd
16
03/15/01, 9:24 AM
Going to a waypoint:
1. Press the NAV Key.
2. Highlight ‘Go To Point’ then press the ENTER Key.
3. Highlight ‘Waypoints’ then press the ENTER Key.
4. Highlight ‘MAP 1’ then press the ENTER Key.
5. Highlight the Goto Button then press the ENTER Key.
The GPSMAP 76 is now navigating to the waypoint MAP 1.
For a GPS to navigate it has to be moving, fortunately you can simulate
movement in the GPSMAP 76. Press the PAGE Key until the Pointer Page is
displayed. Along the top of the Pointer Page there are several data fields, the
Speed Field is located in the upper left corner. To simulate movement, press the
ROCKER Key up one time. This will set a speed of 10 miles per hour. If you
continue to press or hold the ROCKER Key, the speed will increase in 10 mph
increments. For our purpose, 10 mph is fine.
On the Pointer Page are a Pointer and Compass Ring. The Pointer will always
point toward your destination (Bearing) while the Compass Ring reflects the
direction that you are traveling (Track). In short, when you are headed directly
toward your destination, the Pointer will be pointed toward the top of the display,
aligned with the vertical line on the Compass Ring. If you are no longer heading
toward your destination, the Pointer will turn away from the top of the display
to point toward your destination. To get headed toward your destination again,
turn until the Pointer is realigned with the vertical line in the Compass Ring and
pointed toward the top of the display.
The simulator will let you change the Track so that you can see what will
happen. Press the ROCKER Key to the right until your Track has changed about
40°. This will simulate a direction change to the right. The Pointer should now
be pointed toward the left of the display indicating that you need to turn to
the left to head toward the waypoint. This is exactly what will happen during
actual navigation.

03/15/01, 9:25 AM
Press the ROCKER Key to the left simulating a left turn, until the Pointer
is realigned with the vertical line in the Compass Ring. You are now headed
toward the waypoint.
Getting Started
Now that we have now gone through the basic operation of the unit using the
simulator, it is time to do some actual navigation!
Initializing the GPSMAP 76
To turn off the simulator:
1. With the GPS Information Page displayed, press the MENU Key.
2. Select ‘Stop Simulator’ then press the ENTER Key.
Before the GPSMAP 76 can be used for navigation the receiver has to be
initialized. This process is automatic and will only take a few minutes.
Take the unit outside where it will have an unobstructed view of the sky and
turn it on. The unit will search for satellite signals and begin to gather, and store
the information that it needs to become operational. This process should take
no more than five minutes. When the unit is operational the message ‘3D GPS
Location’ will be displayed on the GPS Information Page.
If for some reason the unit is not able to gather the necessary satellite
information an options page will be displayed. Select ‘New Location’ then
‘Automatic’ and allow the unit to continue initializing. This selection will force
the unit to search for satellites. It may take a little longer for the unit to become
operational using this method.
Turning off the Simulator
Starting to navigate
With the unit on and displaying ‘3D GPS Location’ on the GPS Information

Begin walking holding the GPSMAP 76 in front of you with the top of the
unit pointed toward the sky. As you move, you will see that the unit leaves a
bread crumb trail on the map indicating where you have been. Walk at least a
two minutes in one direction and then make either a right or left turn. Continue
walking in this new direction for approximately another two minutes.
Let’s start the trip back. Remember that GPS provides you with direct, straight
line navigation. It is not always possible to navigate using the most direct route,
don’t worry, the GPSMAP 76 will continuously update your Track and Bearing,
always pointing out the shortest route to your destination.

Congratulations, you should have enough basic knowledge of your GPSMAP
76 to begin navigating on your own. Be safe; remember that while the GPS is very
reliable, you should always have a backup means of navigation.

Initializing the GPS Receiver
Initializing the GPS Receiver
Before the GPSMAP 76 can be used for navigation, the GPS receiver must be
initialized. The GPS receiver should only need to be initialized the first time the
unit is used, or if it has been stored several months.
The GPSMAP 76 stores orbital data for each satellite in an Almanac. The
orbital data is supplied in the satellite signals. Each time the unit is used, the
Almanac is updated. This is how the GPSMAP 76 knows which satellites to
search for. If you do not use your GPS for several months, or move the unit
several hundred miles between uses, the Almanac can become “cold”, that is
to say that the orbital information is no longer valid. If the Almanac is “cold”,
your unit may have trouble locking on to satellite signals. If the unit is unable
to receive enough satellite signals to determine its Location’, it will display an
options menu.
Initializing the GPS Receiver:
1. With fresh batteries installed, take the unit outside where a clear 360° view
of the sky can be obtained.
Ready to Navigate
2. Turn the unit on and hold it in front of you with the top of the unit
tilted upward. Follow the screen prompts, pressing PAGE to display the GPS
Information Page.
3. The initialization process is automatic. It should take the GPSMAP 76
no longer than five minutes to acquire enough satellite signals to become
operational. When the unit is able to navigate, it will display either 2D GPS
Location or 3D GPS Location in the Receiver Status Field.

If the GPSMAP 76 is unable to determine its location’, an options menu will
be displayed. Depending on the situation, select an option to help the unit
acquire satellites. To select an option, place the highlight over the option then
press ENTER.
Start Simulator — The Simulator can be used when you are indoors and the
GPS is unable to locate satellites. When you select ‘Simulator’, the GPS
receiver is turned off saving battery power.
New Location — If you have moved the unit to another state, province, or
country, and you are having trouble locking onto satellite signals select ‘New
Location’.
When you select ‘New Location’, another menu will be displayed. This menu
contains the options ‘Automatic’ or ‘Use Map’. If you select ‘Automatic’ the
unit will switch to the AutoLocate mode and begin searching for satellites. If
you select ‘Use Map’ you can use the Pointer on the Map Page to select your
approximate location and the unit will continue to acquire satellites normally.
‘Automatic’ may take longer to acquire satellites.
Stored w/o Batteries — If you have stored the unit without batteries the date
stored in the GPS may be incorrect. To check the date, highlight ‘Stored w/o
Batteries’ and verify the date displayed. If the date is incorrect select ‘Stored
w/o Batteries to search for satellites.

GPS Information Page
When the GPS is receiving at least three satellite signals, it will provide you
with the current GPS Speed, and the estimated Accuracy of the GPS Location.
The GPS must be receiving at least four satellite signals to report the Elevation.
Current GPS Receiver status
The current status of the GPS receiver will always be displayed.
Autolocate — Forces the receiver to search for each satellite individually.
Acquiring Satellites — The receiver will begin in this mode each time the unit
is turned on. The GPS receiver will remain in this mode until it has acquired
at least 3 satellite signals.
2D GPS Location — Indicates that the receiver is only using three satellite
signals. When a 2D GPS Location is achieved, the GPS will display your
current position but is incapable of providing an altitude reading.
3D GPS Location — Indicates the receiver is currently using at least four
satellite signals and is capable of providing your current position and altitude.
2D Differential Location — Indicates the receiver is using DGPS or WAAS
differential data on three satellites.

Satellite Location
The location of each available satellite is displayed over two location rings.
The outer ring represents the horizon, the inner ring represents 45° above the
horizon and the center represents directly overhead. When the unit is using
a satellite for navigation, the satellite number will become highlighted on the
location rings. The unit can be set to display satellite location with North, or your
current track toward the top of the display.

GPS Information Page
Satellite Strength Indicator Bars
The Satellite Strength Indicator Bars not only show the strength of the signal
being received, they also show the status of the signal. The bars will be either
shaded with a light grey, or filled with solid black. If the bar is grey, it means
that the GPS is receiving a signal from the satellite and is in the process of storing
orbital data provided in the GPS signal. When the bar turns solid black, the GPS
is using the satellite signal for navigation. A “D” in or above the bar means that
differential corrections are being applied to that satellite.
Date, Time and Current Location
The GPS gets date and time information from the satellites. The satellites
are equipped with an atomic clock that is very accurate. Since the GPS clock
is derived from timing information sent from the satellite, the GPS clock is also
very accurate.

‘WAAS’ — WAAS is an acronym for “Wide Area Augmentation System”. You
can use the WAAS capability of the GPSMAP 76 to increase the accuracy
to approximately 3 meters. When enabled the GPS receiver searches for a
WAAS satellite, then receives data that will help correct differentials in the
GPS signal. When the unit is using WAAS data, a “D” will be displayed in
the Satellite Strength Indicators on the GPS Information Page, and the receiver
status will indicate a 2D or 3D Differential Location.
Currently the WAAS system is not fully operational and there are only two
satellites in place, one over the Pacific Ocean and one over the Atlantic Ocean.
You must have a clear unobstructed view of the sky for the GPSMAP 76 to
be able to receive a WAAS signal, even then, at times it may not be possible
to receive a WAAS signal. WASS satellites are not received in Battery Saver
Mode.

The ‘User UTM Grid’ will let the user define a grid for a
location format. The user will have to know the Longitude
Origin, Scale, False Easting, and False Northing to create
the grid.
For more information on grids and datums, we recommend that you visit the National Imagery and Mapping
Agency at http://www.nima.mil
The ‘Location’ Tab contains the settings for ‘Location Format’, ‘Map Datum’,
‘North Reference’ and ‘Magnetic Variation’. The settings are used in related fields
throughout the unit.
‘Location Format’ — There are 28 different formats to choose from. See the
sidebar for a list of the formats. You should not need to change the format
unless you are using a chart or paper map for navigation. If so, find the
format that most closely matches your chart or map.

‘Map Datum’ — Datums are used to describe geographic positions for survey-
ing, mapping, and navigation and are not actual maps built in the unit.
Although there are over 100 datums available to choose from, you should
only need to change the Map Datum if you using a chart or paper map that
specifies a different datum in the legend.

WARNING: Selecting the wrong map datum can result in substantial
position errors. When in doubt, use the default WGS 84 datum for
best overall performance.

‘North Reference’ — Let’s you select the reference used in calculating heading
information. You can select from, ‘Auto’ ‘True’, ‘Magnetic’, ‘Grid’ or ‘User’.
‘Auto’ provides magnetic north heading references which are automatically
determined from your current location. ‘True’ provides headings based upon a
true north reference. ‘Grid’ provides headings based on a grid north reference
(used in conjunction with the grid location formats described on page 56).
‘User’ allows you to specify the magnetic variation at your current location, and
provides magnetic north heading references based on the value you entered.
F
WARNING: If ‘User’ is selected, you must periodically update the
magnetic variation at your present position. Failure to update this
setting may result in substantial differences between the information
displayed on your unit and external references, such as a magnetic
compass.
Setup Menu — ‘Location’ Tab
‘Magnetic Variation’ — displays the magnetic variation at your current location. If ‘User’ is selected for the ‘North Reference’, this field is used to enter

The Interface Tab contains one field, ‘Serial Data Format’. This field contains
eight settings that allow the GPSMAP 76 to communicate with computer software
and other electronic devices.
• GARMIN — Allows the GPSMAP 76 to communicate with GARMIN software
and other GARMIN GPS units.
• GARMIN DGPS — Allows the GPSMAP 76 to communicate with GARMIN
Differential Correction devices. The unit can have the beacon receiver scan
for available DGPS beacon or can tune the beacon receiver to the frequency
and bit rate of a nearby DGPS beacon.
• NMEA — Causes the unit to transmit NMEA data. It also allows the
GPSMAP 76 to accept NMEA data from another NMEA device, like a
echo sounder. The baud (speed of communication in bits per second) is
displayed in the Baud field.
• Text Out — Allows the GPSMAP 76 to output simple text data that includes,
date, time, position, and velocity information. The Baud can be set to 1200,
2400, 4800, or 9600 bps.
• RTCM In — Allows the GPSMAP 76 to accept DGPS information from a
device supplying RTCM data in a SC-104 format. The Baud can be set to
1200, 2400, 4800, or 9600 bps.
• RTCM In/NMEA Out — Functions the same as the ‘GARMIN DGPS’ setting
except, the unit will output NMEA 0183, version 2.3 sentences, GPRMC,
GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRTE, and GPWPL.
• RTCM In/Text Out — Functions the same as the ‘RTCM In’ setting except,
the unit will output simple text data that includes date, time, position,
and velocity information. The Baud can be set to 1200, 2400, 4800, or
9600 bps.
• None — Turns off all serial communication.

The temperature rating for the GPSMAP 76 may exceed the usable range of some batteries. Alkaline batteries can rupture
at high temperatures. Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium
batteries when operating the GPSMAP 76 in below-freezing conditions. Extensive use of screen backlighting will significantly
reduce battery life.

Loran TD System
LORAN C is a radio navigation aid operated and maintained in the United
States by the United States Coast Guard. The name LORAN is an acronym for
“LOng RAnge Navigation”. The LORAN system covers the entire United States
and the U.S. Coastal Confluence Zone. From the perspective of a mariner, the
system is used for ocean and coastal navigation. It can be used as a supplemental
system for harbor and harbor approach navigation, and it is used for inland
navigation by recreational vehicles.

Loran TD
LORAN TD Feature
The LORAN TD (Time Delay) feature eases the transition from using LORAN
to using GPS. The GPSMAP unit automatically converts GPS coordinates to
LORAN TDs for those who have a collection of LORAN fixes for favorite fishing
spots and other waypoints recorded as TDs. You can display your position as a TD
or enter waypoints as TDs. The accuracy to be expected from this conversion is
approximately thirty meters. When the unit is placed in the LORAN TD format
mode, it simulates the operation of a LORAN receiver. Position coordinates may
be displayed as TDs, and all navigation functions may be used as if the unit was
actually receiving LORAN signals.
Using the LORAN TD Format
When creating new waypoints using LORAN TD coordinates, you must set
the correct LORAN chain number and secondary stations in the Setup TD field
before storing the waypoint. After the waypoint is stored in unit memory, it
will always reference the LORAN chain number and secondary stations currently
selected in the Setup TD field. If you enter a different LORAN chain number,
change the secondary stations or offsets in the Setup TD field, the active waypoint
information will reflect those changes. Since the GPSMAP unit does not rely on
the LORAN signal for navigation, it can reference a different GRI chain and/or
secondary stations and still navigate to the location stored in memory.

ENTER/MARK, select/enter the desired setting then press ENTER/MARK.
3. When done, press the QUIT key to return to the Status Page.
If the active GRI Chain, secondary stations or offsets have been changed since
the waypoint was created, the waypoint will now reference the active GRI-chain
and secondary stations and adjust the TD coordinates accordingly. Remember that
the GPS is not relying on the LORAN signal for navigation and actually converts
the TD coordinate to a useful LAT/LON coordinate before storing the waypoint to
memory or using it for navigation. Because of this the unit can navigate to a TD
coordinate anywhere in the world.
