The Auto Squelch feature is available only when the
optional Remote SPK/MIC is connected. It has an Off
setting and 3 preset squelch levels:
oFF - Auto Squelch OFF
1 - max sensitivity (min squelch)
2 - med sensitivity (med squelch)
3 - min sensitivity (max/tight squelch)
It requires no adjustment.
1. Press
[SQL/MON]
on the Remote SPK/MIC. The squelch setting flashes.
2. Rotate the channel knob at the base or press on the Remote SPK/MIC to
change the setting. RSQ icon displays when Auto Squelch is active. If tight squelch
is selected SQT icon will also flash.
3. Press

Think of the squelch control
as a gate. If you turn Squelch
fully clockwise it raises the
‘Squelch gate’ so high that no
signals get through.
