Kenwood TM-3530A - Manual (Page 11)

d|) SQL (Squelch) control
To eliminate receiver noise during no-signal period,
slowly adjust the SQL control clockwise until the
noise disappears and the C.TUN indicator goes off
(threshold point).
When a signal is received, the squelch will open, the
C.TUN indicator will light and the speaker will oper­
ate. If the signal is weak or fades during mobile opera­
tion, readjust the squelch for constant reception. For
scan operation, this control must be set to the thre­
shold point.
® POWER/VOL control
Power ON/OFF switch and volume control are com­
bined. Turning the control fully counterclockwise will
turn the power OFF. Clockwise rotation will increases
the audio output.
