Adjusting the squelch threshold – “Squelch”
Adjustment range: 5 to 25 dB
μV, adjustable in 2-dB steps, can be switched
off
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.
The squelch should only be switched off for servicing purposes. With the
squelch threshold set to “
5 dB ”, you switch the squelch off by keeping the
DOWN rocker button pressed for 3 seconds.
If you have accidentally switched off the squelch:
̈
Press the UP rocker button to switch the squelch on.
CAUTION! 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
PHONES to the
minimum (see page 9).
̈
Never change the squelch threshold during a live
transmission.
A high squelch threshold reduces the transmission range.
