Initial Installation
NOTE: By using the optional separation kit EDS-9, you can use the front panel and the main unit in
separate positions. The instruction manual for remote placement is provided with the EDS-9.
Front Panel
The main unit can be set with either side facing up. This can facilitate your ability to hear the
speaker clearly. Position the front panel as you prefer.
1.Slide the front panel while keeping the tab pressed.
2.Turn the front panel, being careful to keep the cable free from kinks.
3.Match the catch in the main unit with the slot in the front panel and fit the front
panel into the main unit.
4.Slide the front panel until it locks securily in place.

Initial Installation
External power control function
1.Be sure the vehicle has a negative-ground, 12VDC electric system before installa-
tion. Connect the provided DC cable with fuse-holder directly to the battery (red
cable to the positive terminal) to minimize any possible ignition noise. Be sure the
vehicle has a large capacity battery as the use of a transceiver may overload the
electric system of the vehicle.
2.In addition, if the optional ignition-key ON/OFF feature is desired, use the provided
ACC cable. Remove the cover by unscrewing 4 screws. Connect the ACC cable to
the ACC power jack (CN11) on the rear side of the circuit board  unit, position the
outgoing cable as shown above, select the ACC switch (SW11) to ACC position and
reassemble the cover.
3.When installing, be sure to disconnect the battery cables of the vehicle and be sure
the ignition key is in the “OFF” position. Connect the ACC cable to the ACC termi-
nal or ACC switch on the vehicle. Make sure the above sequence has been done
properly. Reconnect the vehicle’s electric system.
4.If this option is selected, the unit can be turned on/off either manually or automati-
cally in accordance with the ignition key position.
A: When the ignition key is turned to ACC or ON (“run”) position with the unit left
turned ON, the unit will turn on automatically and turns OFF when the ignition
key is turned to the OFF position.
B: To manually turn the power on/off, leave the ignition key in the ACC position
and use the PWR switch on the unit. If the ignition key is in the OFF position the
unit wont turn on. The power consumption of this feature is about 5mA regard-
less of the ignition key position. For operation without this option, always use
the PWR switch to turn the unit on/off and set SW11 to “on”.

WARNING:The connection of cables may involve certain knowledge about the ve-
hicle into which the unit will be installed. Consult with your car-dealer or
service station for more information if necessary, as we are not respon-
sible for any damage this installation might cause to your vehicle.

Initial Installation
Power supply voltage display function
After connecting the transceiver to a power supply, the supply voltage can be conf irmed by press-
ing the SQL key together with the FUNC key. The supply voltage to the transceiver is then seen on
the display.
The transceiver will return to its normal display when any key is pressed.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
(Example) In case of 13.6V
IMPORTANT:The range of the displayed voltage is only from 7 - 16VDC. Because the displayed
value is estimated, please use a voltmeter when a more precise reading is desired.

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 control.
Switching the MAIN band
Pressing the BAND key will switch the MAIN band between
the VHF band and the 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.
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 on the SUB band
To set the squelch level on the SUB band, 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.
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 settings other than the fre-
quency and S meter are indicated. 
						

							16
Basic Operations
VFO mode
VFO tuning is set as the default mode at the factory. VFO
(variable frequency oscillator) allows you to change the fre-
quency in accordance with the selected channel step as you
rotate the main dial or by using the UP/DOWN keys on the
microphone. VFO mode is also used to program the data to
be stored in the memory channels or to change the parameter
settings of the transceiver.
1.Identify the current mode by checking the dis-
play. If  a “M” or “C” icon is NOT displayed
on it, the unit is already in the VFO mode.
If memories have not been programmed, the unit
cannot be switched to the memory mode.
2.Otherwise press “V/M” key until those icons
are gone.
Changing frequency by channel step
Rotate the main dial clockwise to increase the frequency, coun-
terclockwise to decrease. The UP/DOWN keys on the micro-
phone act in the same way.
Changing frequency by 1 MHz step
This will enable a quick change of frequency in 1 MHz steps:
1.Press MHz key. The digits after 100 kHz will
disappear from the display.
2.Follow the same sequence as above to change
the value.

Basic Operations
Setting the channel step
1.When the unit is in VFO mode, enter into the
SET mode and select the channel step setting
display. (Refer to page 26 to 28 for SET mode).
2.The current channel step will be displayed.
3.You can change the channel step as below by
rotating the dial.
4.Pressing any key other than the FUNC key or
SQL key on the unit will complete the setting
and the display will return to the original sta-
tus.
