Radio Inhibit; Global Positioning System/Global Navigation Satellite System - Motorola APX Series User Manual

Companding
Reduces the channel noise, such as OTA transmission
that is predominantly present in UHF2 and 900 MHz
channel with the following features.
Compressor
Reduces the background noise flow and the speech
signal at transmitting radio.
Expander
Expands the speech while the noise flow remains the
same at receiving radio.
Random FM Noise Canceller (Flutter Fighter)
Reduces the unwanted effects of random FM noise
pulses caused by channel fading under high Signal-to-
Noise (S/N) conditions such as in a moving
transportation. The fading effects, heard as audio pops
and clicks, are canceled without affecting the desired
audio signal.
The Random FM Noise Canceller operates only in
receive mode.

Radio Inhibit

This feature allows the system administrator to put a radio
into a non-functional state when the radio is missing or in
an unknown hand. The radio stays in this state regardless
of power changes, for example, battery removal.
NOTICE:
If the radio has Inter-system roaming capability, the
system administrator is able to put the radio into a
non-functional state when missing radio roamed to
another system.
The radio can only be uninhibited by receiving an
uninhibit command from the system administrator or
reprogram the radio through labtool or depot CPS
only.
Global Positioning System/Global
Navigation Satellite System
The Global Navigation Satellite System (GNSS) in the radio
uses information from the Global Positioning System (GPS)
to determine the approximate geographical location of your
radio. The geographical location is expressed as latitude
and longitude or Military Grid Reference System (MGRS)
format per request from customers.
