The squelch eliminates annoying noise when the transmitter is switched
off. It also suppresses sudden noise when there is no longer sufficient
transmitter power received by the receiver.
왘
Adjust the squelch threshold – with the transmitter switched off – to
the lowest possible setting that suppresses hissing noise.

CAUTION! Danger of hearing damage and material damage!
If you switch the squelch off or adjust the squelch threshold to a very low
value, loud hissing noise can occur in the receiver. The hissing noise can be
loud enough to cause hearing damage or overload the loudspeakers of
your system!
왘
Always make sure that the squelch is switched on (see below).
왘
Before adjusting the squelch threshold, set the volume of the head-
phone output (see page 21) and the audio output level (“
AF Out ”, see
page 37) to the minimum.
왘
Never change the squelch threshold during a live transmission.
