Adjusting the squelch threshold – “Squelch”
Adjustment range: 5 to 25 dBμV, 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.
