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.
