Adjusting the squelch threshold (receiver only)
SQELCH
The receiver is equipped with a squelch that can be adjusted via the "SQELCH"
menu. The squelch eliminates annoying noise when the transmitter is
switched off. It also suppresses sudden noise when there is no longer
sufficient transmitter power received by the receiver.
There are three possible squelch settings:
LO
MID
HI
Selecting the setting "LO" reduces the squelch threshold, selecting the
setting "HI" increases the squelch threshold. Adjust the squelch threshold –
with the transmitter switched off – to the lowest possible setting that
suppresses hissing noise.

channel bank.

Note:
Before adjusting the squelch threshold to a different setting, use the
volume control to set the volume for the connected headphones to the
minimum.
