SQELCH	Adjusting the squelch threshold
	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.
	Note:
	Before adjusting the squelch threshold to a different setting, use
	the volume control to set the volume for the connected head-
	phones to the minimum.

There are three possible squelch settings:

y SQ LO	=	low
y SQ MID	=	middle
y SQ HI	=	high

Selecting the setting “SQ LO” reduces the squelch threshold, select- ing the setting “SQ HI” increases the squelch threshold.

Adjust the squelch threshold – with the transmitter switched off

– to the lowest possible setting that suppresses hissing noise.
