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.

INOTE: Do not try to navigate using the Simulator Mode. While in the 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 find that you are lost,

or if you start a function that you really did not want, just press the PAGE or

QUIT Key.

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 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.

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.

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.

1.Press the ROCKER Key to the left to clear the field.

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.

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 fields in the GPS 76.

Here are a couple of tips:

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. Remember, use the ROCKER Key to move to the next placeholder.

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.

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 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.

The Pointer Page displays a Pointer and a 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.

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 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.

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.

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.

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.

The Reference Section of this manual will describe the Main Display Pages and their options in detail. The Getting Started section described the process of navigating the Main Display Pages and the Option Menus. While this section will provide some direction on how to select an item, its main intention is to describe each Main Page and it’s Option Menu in detail.

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 first 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.

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 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 GPS 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.

Continue Acquiring — Select this option if you are in an area where the satellite signals are being temporarily blocked.
