Set the
SQL
control fully counterclockwise, rotate the
VOL
control out of the click-stop and adjust for a com-
fortable volume on the noise or received signal. The
BUSY/TX
indicator LED should glow green. If a sig-
nal is present, rotate the
DIAL
selector on the top panel
to a channel where only noise is heard.
Adjust the
SQL
control just to the point where the noise is silenced and the LED is extin-
guished. If the
SQL
control is set further clockwise, sensitivity to weak signals will be
reduced. Now, whenever a signal reaches the receiver that is strong enough to open the
squelch, the indicator will glow green.
