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.

왘 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.

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!

왘 Always make sure that the squelch is switched on.

왘 Before adjusting the squelch threshold, set the

volume of the headphone output PHONES to the

minimum

(see page 13)

왘 Never change the squelch threshold during a live

transmission.

A high squelch threshold reduces the transmission range.
