COMPANDING
Companding is a collective term to define
compressing the audio signal on transmission and
expanding the audio signal on reception. The
overall effect is to reduce noise in the received
signal, giving you crisper, clearer audio clarity.
Companding should only be used when other radios
in your system have the same companding feature
available.
You can switch Companding On or Off by using a
pre-programmed Companding button.
1.
Press the Companding button to switch Com-
panding on, when the feature enable alert will
sound.
2.
Press the Companding button again to switch
Companding off, when the feature is disabled
an alert will sound.
LOCAL / DISTANCE
Distance is the standard mode of operation, and
maximises receive radio range.

close proximity and is typically used for base station
configurations.

using a pre-programmed Local/Distance button.

Local when the feature enable alert
