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.
NOTICE:
This feature must be preprogrammed by a qualified radio technician. Check with your
dealer or system administrator for more information.

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 its power changes.
NOTICE:
If the radio has Inter-system roaming capability, the system administrator is able to put the radio
into a non-functional state when the missing radio roams to another system.
The radio can only be uninhibited by receiving an uninhibited command from the system
administrator.

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.
NOTICE:
This feature is addressed as GPS across the manual as the naming convention of the
buttons and strings remain the same as the legacy feature of GPS.
The availability and accuracy of this location information (and the amount of time that it takes to
calculate it) varies depending on the environment in which you are using the GPS feature. For
example, GPS location fixes are difficult to obtain indoors, in covered locations, between high
buildings, or in situations where you have not established a clear broad view of the sky.
If 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.
6.18.1
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:
• 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 the
open sky.
6.18.2
The Outdoor Location Feature (Using GPS)
This feature allows you to determine your current location using a location menu, and your current
distance and bearing in relation to another location. Radio location may be requested and reported
over-the-air.
