Remember that:
1. There are three cellular Number Assignment
Modules (NAM’s) on the NavTalk Pilot. Two
modules are reserved for ground cellular service and
one for AirCell service which is pre-programmed at
the factory.
2. If you want to use AirCell as your cellular provider
on the ground, you may subscribe to AirCell’s
ground cellular system. Otherwise, you may want to
have your ground cellular phone number “Call
Forwarded” to your NavTalk Pilot AirCell number to
eliminate the need to provide potential callers with
two phone numbers.
3. You need to have your battery pack charged and
installed prior to taking your NavTalk Pilot to a
Service Provider. Be certain to take along the trickle
charger in the event that the service provider can
not program your unit immediately.
4. Be certain to give the service provider the Service
Provider Instruction Card packaged with your
NavTalk Pilot. This will tell the service provider how
to access special programming information needed
to assign a phone number to the NavTalk Pilot.
5. The service provider will ask you questions about
the type of service options you desire and then
program your NavTalk Pilot accordingly.
GPS Navigation Overview
The Global Positioning System (GPS) is a system of
24 satellites that circle the earth twice a day in a very
precise orbit and transmit information to earth.
The NavTalk Pilot must continuously “see” at least
three of these satellites to calculate your position and
track your movement. At times, additional satellites may
be needed to determine a position.
By using an almanac (a timetable of satellite numbers
and their orbits) stored in the receiver’s memory, the
NavTalk Pilot can determine the distance and position of
any GPS satellite and use this information to compute
your position.
Important!
For problems with air cellular
service, or if you wish to
change your air cellular
number, contact AirCell at
