Getting Started

While learning the basic operation of the GPS 76, let’s put the unit into
Simulator Mode. The Simulator Mode is great for practicing with the unit while
inside and satellite signals are not available. When the GPS 76 is in Simulator
Mode, the GPS receiver is turned off (this will help conserve battery power) and
the unit cannot be used for actual navigation.

NOTE: Do not try to navigate using the Simulator Mode. While in the

I

Simulator Mode, the GPS receiver is turned off. Any Satellite Signal
Strength Indicators displayed are only simulations and do not indicate
the strength of actual satellite signals.

Activating the Simulator Mode

Press the POWER Key to turn the unit on. The Welcome Page will be
displayed, press the PAGE Key twice to display the GPS Information Page.

Putting the GPS 76 in Simulator Mode:

1. With the GPS Information Page displayed, press the MENU Key.

2. Using the ROCKER Key, highlight ‘Start Simulator’ then press the ENTER Key
to accept your selection.

When the Simulator Mode is active, the message ‘Simulating GPS’ will be

displayed along the top of the GPS Information Page.

The Interface Keys are your link with the GPS 76. Let’s take a few minutes

and see what some of the Interface Keys are used for.

With the GPS Information Page displayed, press the PAGE Key several times.
Notice that each time you press the PAGE Key the next main page will be
displayed. Do the same with the QUIT Key. Notice the QUIT Key acts the same
as the PAGE Key except the pages are displayed in a reverse sequence. Press the
PAGE Key until the Map Page is displayed.

Each main page has an Options Menu. This Options Menu contains the
setup options, and/or functions that apply to that page.

To display the Options Menu:

1. Press the MENU Key.

Selecting an item on the Options Menu:

1. Using the ROCKER Key, highlight ‘Setup Map’.

2. Press ENTER.

Many of the Option and Setup menus in the GPS 76 are arranged in a ‘Tab’
layout. Use the Left /Right ROCKER Key to move from Tab to Tab.

We will look at the options in depth in the Reference Section of this manual.
For now press either the PAGE or QUIT Key. Notice that either of these Keys
stops the current function and returns you to the main page. This is good to
know as you are learning how to use this unit. If you fi nd that you are lost,
or if you start a function that you really did not want, just press the PAGE or
QUIT Key.

Entering Data

Symbol Field

Mark Waypoint Page

Name Field

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.

Let’s combine a couple of lessons. We will create a new waypoint, enter a
waypoint name, and assign a symbol to the waypoint.

The term ‘Waypoint’ may be new to you. You will fi nd 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.

Creating or ‘Marking’ a waypoint with the GPS 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 GPS 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.

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.

14

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 fi rst zero will be highlighted.

Notice that there are now ten placeholders for alpha-numeric characters displayed.

1. Press the ROCKER Key to the left to clear the fi eld.

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 fi nished renaming the waypoint you will need to store it in

the units’ memory.

To store the waypoint:

1. Using the ROCKER Key, highlight the ‘OK’ Button and press the ENTER Key.

These are the same steps that you will use to enter names and change numbers

and select options in all of the fi elds in the GPS 76.

Here are a couple of tips:

1. If you press and hold the ROCKER Key while scrolling through the alpha-
numeric 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 fi nished entering the data.
Remember, use the ROCKER Key to move to the next placeholder.

Map Pointer

You should now have enough knowledge to navigate through the main pages,

Option Menus and enter data into your GPS 76. Now let’s learn how to navigate!

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.

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 800 ft.
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.

16

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 GPS 76 is now navigating to the waypoint MAP 1.

For a GPS to navigate, it has to be moving, and fortunately you can simulate
movement in the GPS 76. Press the PAGE Key until the Pointer Page is
displayed. Along the top of the Pointer Page there are several data fi elds. 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 fi ne.

The Pointer Page displays a Pointer and a Compass Ring. The Pointer will
always point toward your destination (Bearing) while the Compass Ring refl ects
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.

Getting Started

Initializing the GPS 76

Turning off the Simulator

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.

Now that we have now gone through the basic operation of the unit using the
simulator, it is time to do some actual navigation!

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 GPS 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 fi ve 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.

Starting to Navigate

With the unit on and displaying ‘3D GPS Location’ on the GPS Information
Page, mark a waypoint at your current location. Name this waypoint ‘HOME’,
assign the ‘Residence’ Symbol and store the waypoint.

18

Before we take off walking lets clear the Track Log. The Track Log is the bread

crumb trail left on the Map Page and Highway Page.

To clear the Track Log:

1 Press the MENU Key twice to display the Main Menu.

2. Highlight Tracks then press the ENTER Key.

3. Highlight the ‘Clear’ Button then press the ENTER Key.

4. Highlight the ‘Yes’ Button then press the ENTER Key.

5. Press the PAGE Key until the Map Page is displayed.

Begin walking holding the GPS 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 for at least 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 GPS 76 will continuously update your Track and Bearing, always
pointing out the shortest route to your destination.

To begin navigation:

1. Press the NAV Key.

2. Select ‘Go To Point’ then press the ENTER Key.

3. Select ‘Waypoints’ then press the ENTER Key.

4. Select ‘HOME’ then press the ENTER Key.

5. With the ‘Goto’ Button highlighted, press ENTER.

The GPS provides a straight line, direct navigation course
to your destination. Since it is not always possible to
follow a straight line from start to fi nish, as you move,
the Pointer will always point toward your destination and
the Compass Ring will always show your current track.

When you are able to turn toward the destination, follow
the Pointer until it points toward the top of the display
and aligns with the line in the Compass Ring. When the
Pointer and Line are aligned, your Track and Bearing will
be equal and you will be headed toward your destination.
When you are near your destination, a message ‘Arriving
at Destination’ will be displayed.

As you start walking, you will see that the Pointer is pointed at your destina­tion. As soon as you are able, turn toward the Pointer until it is aligned with
the vertical line in the Compass Ring. As you continue walking, and approach
your HOME waypoint, a message will be displayed alerting you that you have
arrived.

Congratulations, you should have enough basic knowledge of your GPS 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 GPS 76 can be used for navigation, the GPS receiver must be
initialized. The GPS receiver should only need to be initialized the fi rst time the
unit is used, or if it has been stored several months.

The GPS 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 GPS 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.

Getting Started

Reference

Initializing the GPS Receiver:

1. With fresh batteries installed, take the unit outside where a clear 360° view
of the sky can be obtained.

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 GPS 76 no longer
than fi ve 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.

GPS Information Page

The GPS Information Page displays your speed, elevation, the estimated
accuracy, receiver status, satellite locations, satellite signal strength, the date, time
and the GPS receiver’s current location.

Speed, Elevation and Estimated Accuracy

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 —

Acquiring Satellites —

Forces the receiver to search for each satellite individually.

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.
A “D” will be displayed in or above the indicator bar for each differentially
corrected satellite.

2D Differential Location —

Indicates the receiver is using DGPS or WAAS
differential data on three satellites. A “D” will be displayed in or above the
indicator bar for each differentially corrected satellite.

3D Differential Location —

Indicates the receiver is using DGPS or WAAS
differential data on at least four satellites.

Lost Satellite Reception —

Indicates that the GPS receiver has lost satellite

reception.

Simulating GPS

— Indicates the GPS 76 is running in Simulator Mode and the

GPS receiver is turned off. It is important to remember when you are using
the Simulator, the GPS 76 can not be used for actual navigation.

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.

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 fi lled 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.

When the GPS receiver has achieved a 2D or 3D GPS Location, the current
location will be displayed in the selected Location Format.

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 Pacifi c Ocean and one over the Atlantic Ocean.

You must have a clear unobstructed view of the sky for the GPS 76 to be

able to receive a WAAS signal, even then, at times it may not be possible to

receive a WAAS signal.

The temperature rating for the GPS 76 may exceed the usable range of some batteries. Alkaline batteries can rupture at high
temperatures. Alkaline batteries lose a signifi cant amount of their capacity as temperature decreases. Use lithium batteries when
operating the GPS 76 in below-freezing conditions. Extensive use of screen backlighting will signifi cantly 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 Confl uence 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 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 fi xes for favorite fi shing
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 fi eld
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 fi eld. If you enter a different LORAN chain number,
change the secondary stations or offsets in the Setup TD fi eld, the active waypoint
information will refl ect those changes. Since the GPS 76 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.

Loran TD

The LORAN Position Format fi eld is located under the Units tab in the Main
Menu. The ‘LORAN TD Setup’ window contains the fi elds to select the Loran
GRI-Chain Number, Primary and Secondary Stations, and TD Offsets.

To setup Loran TD from the Main Menu:

1. Using the ROCKER, highlight the “Location Format” fi eld on the ‘Location
Tab” and press ENTER.

2. Highlight ‘Loran TD’, press ENTER.

3. To change the settings of any of the fi ve fi elds, highlight the fi eld, press
ENTER select/enter the desired setting then press ENTER.

4. When done, press the PAGE Key to return to the Main Menu.

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.
