4.1 GPS Overview
For an overview of the NavTalk GPS function,
refer to Section 1 on page 1 of this manual.
4.2 Using the GPS Simulator Program
The Simulator is designed to introduce you to
the application of the NavTalk basic GPS features
using a simulated trip. The simulator assumes that
the receiver has been properly initialized as
explained in this section and that you have not
changed any of the factory default settings. If you
have changed any settings (position formats, units
of measure, etc.) the descriptions and pictures in
this section may not match your configura-
tion.
WARNING: Understand that the receiver
does not actually track satellites when in the simu-
lator mode and therefore it should never be used
for actual navigation. The receiver cannot be
turned on with the simulator mode active, so if
you forget to return it to normal operation before
turning the unit off, it will automatically return to
normal operation the next time you use the
NavTalk. However, if you switch from simulated
navigation to the cellular phone mode and then
back to GPS mode, the unit will remain in the
simulated navigation mode.
4.3 Initializing the NavTalk
Before you can use the GPS Receiver it must be
initialized (given an opportunity to determine where
it is located on the globe). To initialize the NavTalk,
take the unit outside and find an open area where the
antenna has a clear view of the sky. Hold the unit at a
comfortable height with the GPS patch antenna par-
allel to the ground.
Since basic operation involves getting acquainted
with the GPS receiver, switch to the Satellite Status
Page if the Cellular Status Page appears by pressing
the GPS/PHONE key.
