Adjusting the squelch threshold
The squelch eliminates annoying noise when the transmitter is switched off or when there is
no longer sufficient transmitter power received by the receiver.
̈
Adjust the squelch threshold – with the transmitter switched off – to the lowest possible
setting that suppresses hissing noise.
Adjustment range: 5 to 25 dB
μV, adjustable in 2-dB steps, can be switched off.
The squelch should only be switched off for servicing purposes. You can switch the squelch
off by turning the jog dial at the 5 dB setting to the left and keeping it in this position for
3 seconds. The dotted lines go off and the audio level display “
AF ” shows full deflection.
If you have accidentally switched off the squelch:
̈
Turn the jog dial to the right to switch the squelch on.

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!
̈
Always make sure that the squelch is switched on.
̈
Before adjusting the squelch threshold, set the volume of the headphone output
(see page 13) and the audio output level to the minimum (“
AF Out ”, see page 22).
̈
Never change the squelch threshold during a live transmission.
If the squelch threshold is adjusted too high, the transmission range will be
reduced.
