General
Manual Scope
This manual is intended for use by experienced technicians familiar with similar types of
communication equipment. It contains all service information required for the equipment
and is current as of the publication date.
Precautions
Safety Standards
● DO NOT operate your radio when someone is either touching or standing within
2 or 3 feet of the antenna, to avoid the possibility of radio frequency burns or
related physical injury.
● DO NOT operate the radio near electrical blasting caps or in an explosive
atmosphere.
● Switch OFF the radio while refueling or parking at gas station.
● Turn off your radio in any place where posted notices instruct you to do so.
● DO NOT modify the radio for any reason.
● DO NOT expose the radio to direct sunlight over a long time, nor place it close to
heating source.
● DO NOT place the radio in excessively dusty, humid areas, nor on unstable
surfaces.
● Refer the service to qualified technicians only.
Operation Safety Guidelines
● For vehicles equipped with electronic anti-skid braking systems, electronic
ignition systems or electronic fuel injection systems, interferences may occur
during the radio transmission. If the foregoing electronic equipments are
installed on your vehicle, please contact your dealer for further assistance to
make sure that the radio transmission will not interfere with these equipments.
● For radio installation in vehicles fueled by LP gas with LP gas container within
interior of the vehicles, the following precautions are recommended for personal
safety.
(1) Any space containing radio equipment shall be isolated by a seal from the
space in which the LP gas container and its fittings are located.
2
(2) Remote (outside) fitting connections shall be used.
(3) Good ventilation is required for the container space.
Installation Safety Guidelines
● Do not mount the mobile radio overhead or on a sidewall unless you take special
precautions.
● If someone were to remove the radio and fail to replace it properly, road shock
could bump the radio loose, and the falling radio could, in some circumstances,
cause serious injury to the driver or a passenger. In a crash, even when properly
installed, the radio could break loose and become a dangerous projectile.

4. Clone Mode
Data can be transferred from radio to radio either by wired cloning or wireless cloning
Wired Clone Mode
1) Press and hold down [P3] to power on the source radio. The radio enters Clone
mode with “ ” displayed on numeric display. Or the radio enters User Mode when
Clone Mode is set OFF by your local dealer.
2) Press [P3] to toggle between Dealer Clone and Factory Clone Mode. “DEACLONE”
or “FACCLONE.” appears on the display when the corresponding mode is selected.
The display reverts to the original after 5 seconds. The Dealer Clone Mode does not
clone adjusted data, embedded information,etc. While Factory Clone Mode clones all
data. The default clone mode is Dealer Clone Mode.
3) Connect the source radio with wired clone cable and power it on.
4) Press [P4] to start cloning. The LED of source radio glows red and the data is
transferred from source radio to the target radio. When receiving data, the target
glows green with “PROGRAM” on LCD. When the cloning is completed, the source
radio displays “END”. The target radio automatically enters user mode after
receiving all data.
5) Press [P4] to return the source radio to clone mode. “CLONE” appears on LCD.
Repeat the above steps to continue wired clone.
Wireless Clone Mode
1 Press [P3] to power on the source radio. The radio enters Clone Mode with “CLONE”
displayed on the display. Or the radio enters User Mode when Clone Mode is set OFF
by your local dealer.
2 Press [P1] to enter Wireless Clone Mode and “WIRELESS” appears on LCD. Channel
frequency of wireless clone displays on LCD after two seconds (proceeding wireless
clone at this frequency). Press [P1] again to return to Clone Mode. Press [Down] to
switch to Wireless Clone channel.
3 Press [P3] to toggle between Dealer Clone and Factory Clone Mode in Clone Mode or
Wireless Clone Mode. “DEACLONE" and“FACCLONE”appears on the display when
the corresponding mode is selected. The display reverts to the original after 5 seconds.
The Dealer Clone Mode does not clone adjusted data, embedded information,etc.
While Factory Clone Mode clones all data. The default clone mode is Dealer Clone
Mode.
4 Repeat step 1-2 to operate the target radio, the frequency is set the same as that of
source radio. Place the target radio next to the source radio and Press [P4] on the
source radio to start cloning.
5) The LED of source radio glows red and the data is transferred from source radio to the
target radio. “ TX 00% ” appears on LCD. 00 bit on the left side of LCD indicates data
cloning rate and increases at a basic unit of one as data is continuously transferred.
The target radio glows orange when receiving data with “ RX 00% ” and “BUSY” icon
13
on LCD. 00 bit on the left side of LCD indicates data cloning rate and increases at a
basic unit of one as data is continuously received.
6) The source radio flashes orange with “END” on LCD after the data transmission. Clone
frequency appears when [P1] is pressed. Repeat the above steps to continue cloning.
While the target radio reverts to Users Mode after receiving all data.
Note: Clone Mode can be enabled/disabled by your local dealer. Cloning is accessible
only when Clone Mode is enabled.
5. Firmware Version Display Mode
Press [P4] to power on the mobile radio and Firmware Version Display Mode appears
on LCD. Release [P4] to enter User Mode automatically.
6. PC Mode
Connect the mobile radio with PC via programming cable. The data can be written
to the radio from PC, and then saved into the EEPROM. Data programming and radio
adjustment are accessible by programming software.
1) “PROGRAMM” appears on LCD after data is transferred to the mobile radio from
the computer. LED glows green when data is written to the radio and red when data is
read from the radio. Radio will restart automatically when programming is completed.
2) The following parameters can be set through the programming software.
● High TX Power
● Low TX Power
● Maximum Frequency Deviation
● CDCSS Balance
● CTCSS Deviation
● CDCSS Deviation
● DTMF Deviation
● MSK Deviation
● Single Tone Deviation
● Rx sensitivity
● Squelch Level 9
● Squelch Level 3
