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!
Always make sure that the squelch is switched on.
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.
Only switch off the squelch for servicing or test purposes.
Adjust the squelch threshold – with the transmitter switched off – to the
lowest possible setting that suppresses hissing noise.
A high squelch threshold reduces the transmission range.
The squelch should only be switched off for servicing or test purposes. With
the squelch threshold set to "Low", you switch the squelch off by keeping the
DOWN rocker button pressed for 3 seconds.
