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.
