Basic Operations

Turning the unit on and off

By pressing the PWR key the power is turned on. By pressing
the PWR key again, the power is turned off. Refer page 9 for
external power supply control.

Switching the MAIN band

Repeating to press the BAND key will switch the MAIN band
between VHF band and UHF band.
The MAIN band allows transmission and reception. The SUB
band only allows reception. The MAIN band and the SUB
band can receive simultaneously.
IMPORTANT: On the SUB side, no setting other than the fre-
quency and S meter is indicated.

Audio Volume level setting

The volume of the MAIN band is adjusted by the VOL knob
on the MAIN side, and the volume of the SUB band by the
VOL knob on the SUB side.
Rotate the VOL knob clockwise to increase the audio level,
counterclockwise to decrease.

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,
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.

Squelch level setting on the SUB side

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