ADVANCED OPERATION

COMP (Compander)

Press the PF button assigned to the “COMP”

function to turn the “Compander” IC ON or OFF.

This IC contains two variable gain circuits con-

figured for compressing and expanding the dy-

namic range of the radio's transmitted audio sig-

nal.

When you enable this function, the signal-to-noise

radio can be improved by reducing the transmit-

ted audio dynamic range.

Encryption (Option)

When the Voice Scrambler feature is enabled,

pressing the assigned PF button of the “Encryp-

tion” toggles the Scrambler on and off.
