Adjust the squelch threshold – with the transmitter switched off – to the
lowest possible setting that suppresses hissing noise.

”, you switch the squelch off by keeping the
DOWN rocker button pressed for 3 seconds.

WARNING
Danger of hearing 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!
왘
Always make sure that the squelch is switched on.
왘
Before adjusting the squelch threshold, set the volume of
the headphone output to the minimum (see page 11).

Never change the squelch threshold during a guided tour.
왘
Only switch off the squelch for servicing or test purposes.
A high squelch threshold reduces the transmission range.

mend to keep this function switched on at all times.
