Initializing the GPS Receiver

The GPSMAP 176/176C must be initialized before it can be used
for navigation. The GPS receiver only needs to be initialized the first
time the unit is used or if it has been stored for several months. This
process is automatic and should only take a few minutes.
The GPSMAP 176/176C stores orbital data for each satellite in an
Almanac. The orbital data is supplied in the satellite signals. Each
time the unit receives satellite signals, the Almanac is updated. If
the unit has not been used for several months or has moved over six
hundred miles between uses, the Almanac can become "cold." If the
Almanac is "cold," the orbital data is no longer valid and your unit
may take longer to lock on to satellites while updating the Almanac.

To initialize the GPS receiver:
1. Take the unit outside where it has an unobstructed view of
the sky and turn it on. Make sure the antenna is pointed up.
Following the screen prompts, press ENTER to display the
GPS Information page.
2. The unit searches for satellite signals and begin to gather and
save the information that it needs to become operational.
3. When the unit is able to navigate, the message 2D GPS
Location or 3D GPS Location is displayed at the top of the
GPS Information page, and the unit automatically switches to
the Map page.
If the unit is unable to gather the necessary satellite information, an
options menu appears. Select New Location, then Automatic and
allow the unit to continue initializing. This selection forces the unit
to search for all satellites. The unit may take a little longer to become
operational using this method.
