WARNING: The connection of cables may involve certain knowledge about the ve-

hicle the unit will be installed. Consult with your car-dealer or service sta-

tion for more information if necessary as we are not responsible of any

damage this installation might cause to your vehicle.

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.

Initial Installation

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 unit inside, trim the outgoing
cable as shown above, select the ACC switch (SW11) to ACC position and reas­semble the cover.

3. Be sure to cut the electric power supply off (by disconnecting the battery cables of

the vehicle) and the ignition key is at OFF position for you and your car's safety.
Connect another end of the ACC cable to the ACC terminal or ACC switch on the
vehicle. Make sure all above sequence has been done properly. Set the vehicle's
electric system back normal.

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 (start) 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 ON/OFF the power, leave the ignition key to ACC position and use

PWR switch on the unit. If the ignition key is at OFF position the unit won't turn
on. The power consumption, regardless of the ignition key position, of this fea­ture is about 5mA. For operation without this option, use the PWR switch to turn
the unit on/off always.

Initial Installation

Power supply voltage display function

After connecting the transceiver to the power supply, the supply voltage can be confirmed by press­ing the SQL key together with the FUNC k e y. The supply v oltage to the transceiver is then seen on
the display.
The transceiver will return to its normal operation when the power is switched OFF.

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

Shift Direction and Offset frequency setting

Conventional repeaters are operated in the DUPLEX mode, which receives an incoming
signal on one frequency and re-transmits on another. The difference between these two fre­quencies is called the offset frequency. The offset is variable between 0 to 99.995MHz on
this unit.

1. After pressing the FUNC key, by pressing MHz

key while [F] appears on the display, the dis­play will show the current status of offset fre­quency and shift direction. By repeating to
press MHz key, shift direction will be changed
as right.

- 0.600 + 0.600

2. By rotating the dial (pressing UP/DOWN key)

while shift frequency is displayed, one click will
change the frequency by one channel step.

3. After pressing the FUNC key, rotating the dial

will change the frequency by 1MHz depend­ing on which direction the dial is rotated (how
UP/DOWN key is pressed).

CALL mode

This is a memory mode that allows the transceiver to quickly recall the assigned memory channel
by simply pressing the CALL key, regardless of the current status of the unit.
The default setting is 145.00MHz/433.00MHz, and available 1ch each on VHF and UHF band.

To recall a CALL channel

Select the desired VHF or UHF band by pressing BAND key.

1. Press CALL key. The C icon appears on the

display and the transceiver enters the CALL
mode. In this mode, the main dial or the UP/
DOWN keys cannot change the frequency or
memory channels.

2. Press CALL key again or press V/M key to exit

CALL mode.

3. No scan functions are available in CALL mode.

To store a desired setting in the CALL channel, follow the memory mode programming instruc­tions and assign your selected settings to memory channel C. The call channel can be modified but
cannot be eliminated or hidden.

Basic Operations

To receive signals

1. Be sure to have the unit connected to the ap-

propriate antenna, powered on, set the audio
volume and squelch level properly on both
MAIN and SUB bands.

2. Select the desired band by pressing BAND key

and browse frequencies or select desired fre­quency to listen to ongoing communications.
The S-meter shows relative signal strength
when the transceiver detects an incoming sig­nal, and RX display lamp (green) turns on.
