30 Basic operation

Hearing faint and noisy signals

Your radio’s squelch allows the radio to unmute only when 
the strength of the incoming signal is above a predetermined 
threshold. This means that only signals of reasonable 
intelligibility are made audible. To make faint and noisy signals 
audible, use the squelch override function to unmute 
the radio.

To activate squelch override and unmute the radio:

Press the function key programmed for squelch override.

While squelch override is on, the green LED flashes 
continually. 

Squelch override remains on until there is a further 
key press.

Turning squelch override on and off by using 
the function key programmed for monitor

The function key programmed for monitor may be 
programmed so that a short key press turns monitor on, and a 
long key press turns squelch override on.

To activate squelch override and unmute the radio:

Press and hold the function key programmed for monitor.

While squelch override is on, the green LED flashes 
continually.

Squelch override remains on until there is a further long 
key press.
