Initializing the GPS Receiver
The GPSMAP 76 needs to be initialized the rst time
the unit is used, if it has been stored several months,
or if it has been moved over 600 miles. The Almanac
within unit stores each satellite’s orbital data that is
supplied in the satellite signals. The GPSMAP 76 uses
the Almanac to know which satellites to search for
and automatically updates each time the unit aquires
satellites. If you do not use your GPS for several
months or move the unit over 600 miles between
uses, the Almanac can become “cold” and the orbital
information is no longer valid. Your unit may have
trouble locking on to satellite signals using a “cold”
Almanac. If the unit is unable to receive enough
satellite signals to determine its location and update the
Almanac, it displays an options menu.
Initializing the GPS Receiver:
1. With fresh batteries installed, take the unit
outside for a clear 360° view of the sky.
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 ve
minutes to acquire enough satellite signals to
become operational. When the unit is able to
navigate, it displays either 2D GPS Location or
3D GPS Location in the Receiver Status eld.

Initialization Options
If the GPSMAP 76 is unable to determine its location,
an options menu is displayed. Select the appropriate
option to help the unit acquire satellites. Highlight the
option and then press ENTER to select.
Start Simulator—is used for practicing with the unit
while inside and satellite signals are not available.
When you select Simulator, the GPS receiver is turned
off saving battery power.
New Location—is used when you have moved the unit
over 600 miles and are having trouble locking onto
satellite signals.
When you select New Location, another menu is
displayed. This menu contains the options Automatic
or Use Map. If you select Automatic, the unit switches
to the AutoLocate mode and begin searching for
satellites. This process may take longer to acquire
satellites. Use Map utilizes the pointer on the Map
page to select your approximate location. Then the unit
continues to acquire satellites normally.
Stored w/o Batteries—is used when the date stored
in the unit may be incorrect due to storage without
batteries. 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—is used when in an area where
the satellite signals are being temporarily blocked.
When initializing the receiver or trying to
receive satellite signals, orient the GPSMAP
76 so the top of the unit points toward the
sky. If the unit is held with the top of the unit
pointed toward the horizon, satellite reception
may be severly degraded.

3. Highlight Waypoints and press ENTER.
4. Highlight the desired waypoint and press
ENTER.
5. Highlight the Goto Button and press ENTER.
The GPSMAP 76 is now navigating to the waypoint.
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
elds, one of which is the Speed eld. To simulate

(Bearing) while the Compass Ring reects the direction
that you are traveling (Track). When you are headed
directly toward your destination, the Pointer is pointing
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 turns 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.
Note: Remember that while the GPS is very
reliable, you should always have a backup means
of navigation.
