Gps Performance Enhancement; Trunking System Controls; Operating In Failsoft System - Motorola APX 8000 User Manual

Keep in mind that the accuracy of the location
information and the time it takes to obtain it varies
depending upon circumstances, particularly the ability
to receive signals from an adequate number of
satellites.
Note
Even where adequate signals from multiple
satellites are available, your GPS feature only
provides an approximate location, usually
within 10 meters from your actual location, but
sometimes farther away.
The satellites used by the GPS feature are controlled
by the U.S. government and are subject to changes
implemented in accordance with the Department of
Defense GPS user policy and the Federal Radio
Navigation Plan. These changes may affect the
performance of the GPS feature on your radio.

GPS Performance Enhancement

Sometimes, the GPS feature may be unable to
complete a location calculation successfully. You then
see a message indicating that your radio cannot
connect to enough visible satellites.
To maximize the ability of your radio to determine a
fix, take note of the following guidelines:

English
• For your initial fix, hold the radio in the face
position.
• Stay in the open. The GPS feature works best
where there is nothing between your radio and a
large amount of open sky.

Trunking System Controls

Operating in Failsoft System

The failsoft system ensures continuous radio
communications during a trunked system failure. If a
trunking system fails completely, the radio goes into
failsoft operation and automatically switches to its
failsoft channel.
During failsoft operation, your radio transmits and
receives in conventional operation on a
predetermined frequency. You hear a medium-
pitched tone and the display shows FAILSOFT.
When the trunking system returns to normal
operation, your radio automatically leaves failsoft
operation and returns to trunked operation.
To continue, in Failsoft, to communicate with other
talkgroups, refer to the following procedure.
