Squelch level setting on the SUB side

To set the squelch level on the SUB side, press the BAND key while [SQL] appears.

1. Press SQL Key.

[SQL] icon appears on the display and the

squelch level will be shown on it.

2. By rotating the main dial or by using the UP/

DOWN keys on the microphone, adjust the

squelch level to the desired level.

The new squelch level will be stored if the power

is turned off.

3. When completing the setting, press PTT or any

key on the front panel other than the Band key.

Then the display will return to the original sta-

tus; or if there are no operations for 5 seconds,

the unit will automatically complete the setting

and the display will return to the original status.

NOTE: • 21 levels, between (00) and (20), are available for the squelch level.

(Higher level settings will make the squelch more difficult to open.)

• The default level is 02.

Squelch level setting

Adjust threshold level of the squelch. A squelch eliminates the background noise when a signal is

not received. To set squelch level on the MAIN band side,

IMPORTANT: On the SUB side, no setting other than the fre-

quency and S meter is indicated.
