Mobile Radio
Thank you for purchasing a COVALUE mobile radio.
This simple to use radio adopts the latest advances in technology, providing
reliable communication in today’s demanding communication environment.
Notices to the User:
When condensation occurs inside the transceiver:
·Condensation may occur inside the transceiver when the room is warmed using a heater
on a cold day or when the transceiver is quickly moved from a cold location to a warm
location.
• When condensation occurs,the microcomputer and /or the transmit/receive circuits may
become unstable,resulting in transceiver malfunction.
• If this happens,turn OFF the transceiver and wait for a while.
• When the condensed droplets disappear,the transceiver will function normally.
Do not touch the metal surface of the transceiver while it is in use.
Do not mount the transceiver such that the chassis can come in contact with skin.
High temperatures may burn your skin.
PRECAUTIONS

Please observe the following precautions to prevent fire, personal injury, and/or
transceiver damage:
• Do not attempt to configure your transceiver while driving; it is simply too dangerous.
• Be aware of local laws pertaining to the use of headphones/headsets while driving on
public roads.
If in doubt, do not wear headphones while mobiling.
• Do not transmit with high output power for extended periods; the transceiver may
overheat.
• Do not modify the transceiver unless instructed by this manual or other COVALUE
documentation.
• Do not expose the transceiver to long periods of direct sunlight nor place it close to
heating appliances.
• Do not place the transceiver in excessively dusty,humid or wet areas, nor on unstable
surfaces.
• If an abnormal odor or smoke is detected coming from the transceiver, turn OFF the
power immediately. Contact a COVALUE service station or your dealer.
• This transceiver is designed for a 13.8 V power source. Never use a 24 V battery to
power the transceiver.

After carefully unpacking the transceiver, identify the
items listed in the table below. We recommend you keep
the box and packaging for shipping.

CHAPTER 1 PREPARATION
MOBILE INSTALLATION
To install the transceiver, select a safe, convenient
location inside your vehicle that minimizes danger to your
passengers and yourself while the vehicle is in motion.
Consider installing the unit at an appropriate position so
that knees or legs will not strike it during sudden braking
of your vehicle. Try to pick a well ventilated location that
is shielded from direct sunlight.
1 Install the mounting bracket in the vehicle using the
supplied self-tapping screws (4), flat washers (4), and
Spring washers (4).
The bracket must be installed so that the 3 screw long
hole
positions on the side of the mounting bracket are towards
The rear of the bracket.
2 Position the transceiver, then insert and tighten
the supplied hexagon SEMS screws (4) and flat
washers (4).
Double check that all hardware is tightened to prevent

vehicle vibration from loosening the bracket or
transceiver.
Determine the appropriate angle of the transceiver, using
the 3 screw hole positions on the side of the mounting
bracket.
MOBILE OPERATION
The vehicle batter y must have a nominal rating of 12 V.
Never connect the transceiver to a 24 V batter y. Be sure
to use a 12 V vehicle batter y that has sufficient current
capacity. If the current to the transceiver is insufficient,
the display may darken during transmission, or transmit
output power may drop excessively.
1 Route the DC power cable supplied with the
transceiver directly to the vehicle's batter y terminals
using the shortest path from the transceiver.
If using a noise filter, it should be installed with an
insulator to prevent it from touching metal on the vehicle.

We recommend you do not use the cigarette lighter
socket as some cigarette lighter sockets introduce an
unacceptable voltage drop.
The entire length of the cable must be dressed so it is
isolated from heat, moisture, and the engine secondar y
(high voltage) ignition system/ cables.
2 After the cable is in place, wrap heat-resistant tape
around the fuse holder to protect it from moisture and
tie down the full run of cable.
3 To prevent the risk of short circuits, disconnect other
wiring from the negative (–) batter y terminal before
Connecting the transceiver.
4 Confirm the correct polarity of the connections, then
attach the power cable to the batter y terminals;
red connects to the positive (+) terminal and black
connects to the negative (–) terminal.
Use the full length of the cable without cutting off excess
e v e n i f t h e c a b l e i s l o n g e r t h a n r e q u i r e d . I n
particular,never remove the fuse holders from the
Cable.
5 Reconnect any wiring removed from the negative
terminal.
6 Connect the DC power cable to the transceiver's
power supply connector.
Press the connectors firmly together until the locking tab
connectors firmly together until the locking tab
clicks

FIXED STATION OPERATION
In order to use this transceiver for fixed station operation,
you will need a separate 13.8 V DC power supply (not
included). The recommended current capacity of your
power supply is 14 A or more.
1 Connect the DC power cable to the regulated DC
power supply and ensure that the polarities are correct
(Red: positive, Black: negative).
· Do not directly connect the transceiver to an AC
outlet.
·Use the supplied DC power cable to connect the
transceiver to a regulated power supply.
·Do not substitute a cable with smaller gauge wires.
2 Connect the transceiver's DC power connector to the
connector on the DC power cable.
Press the connectors firmly together until the locking tab
Clicks
Note:
◆
capabilities,we recommend using the power supply could
output more than 23 A, 25% duty cycle.
◆ Before connecting the DC power supply to the
transceiver, be sure to switch the transceiver and the DC
power supply OFF.
◆ Do not plug the DC power supply into an AC outlet until

you make all connections.
For your transceiver to fully exhibit its performance
REPLACING FUSES
If the fuse blows, determine the cause, then correct the
problem. After the problem is resolved, replace the fuse.
If newly installed fuses continue to blow, disconnect
the power cable and contact your authorized CSI
Dealer or an authorized CSI service center for assistance.
Fuse Location Fuse Current Rating
Transceiver 15 A
Supplied Accessory DC Power Cable 20 A
Note:
If you use the transceiver for a long period when the
vehicle batter y is not fully charged, or when the engine is
OFF, the batter y may become discharged, and will not
have sufficient reserves to start the vehicle. Avoid using the
transceiver under these conditions.
ANTENNA CONNECTION
Before operating, install an efficient, well-tuned antenna.
The success of your installation will depend largely on
the type of antenna and its correct installation. The
transceiver can give excellent results if the antenna
system and its installation are given careful attention.
Use a 50Ωimpedance antenna and low-loss coaxial feed
Line that has a characteristic impedance of 50Ω, to
match the transceiver input impedance. Coupling the

antenna to the transceiver via feed lines having an
impedance other than 50 Ωreduces the efficiency of the
antenna system and can cause interference to nearby
broadcast television receivers, radio receivers, and other
electronic equipment.
ACCESSORY CONNECTIONS
EXTERNAL SPEAKER
If you plan to use an external speaker, choose a speaker
with an impedance of 8 Ω. The external speaker jack
accepts a 3.5 mm (1/8") mono (2-conductor) plug.
MICROPHONE
For voice communications, connect a 600 Ω microphone
equipped with an 8-pin modular plug into the modular

socket on the front of the main unit. Press firmly on the
plug until the locking tab clicks.
Attach the supplied microphone hanger in an appropriate
location using the screws included in the screw set.
PC CONNECTION 1
To utilize the optional PC programming software, you must
first connect the transceiver to your PC using an optional
Programming Cable (via the rear DB15 connector).
Note: Ask your dealer about purchasing a Programming
Cable.
