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 On or Off Companding by

using a pre-programmed Companding button

or via the menu.
