Basic Operation 13
Squelch
The 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.
Monitor
The monitor function is used to check that the channel is
clear before you make a call. While monitor is on, the
green LED flashes continually.
Activating Monitor
1. Press the monitor function key and monitor overrides
the signalling mute, allowing you to hear any traffic
on the channel.
Note: Your radio may be programmed to
activate monitor whenever the microphone
is off the microphone clip.
2. Press the monitor function key again to turn monitor
off, and the green LED no longer flashes.
Activating Squelch Override
1. Press and hold the monitor function key for longer
than one second to override both squelch and the
signalling mute.
This allows you to hear even faint and noisy signals.
2. Press the monitor function key again to return the
radio to a quiet state.
Note: Squelch cannot be overridden when
the radio is scanning.
