Operation

Setting the Manual Squelch

Turn the outer ring of the SQ control at the base to adjust the Squelch.
You must select a channel which is not in use before setting the
SQUELCH control. (see p.19 for "Selecting a Channel").
NOTE
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.

Setting the Auto Squelch

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
change the setting. RSQ icon displays when Auto Squelch is active. If tight squelch
is selected SQT icon will also flash.
3. Press [MENU/ENTER] to store the setting.
