2. Position the transceiver, then insert and tighten the supplied
hexagon SEMS screws.
▼Double check that all screws are tightened to prevent vehicle
vibration from loosening the bracket or transceiver.

Initial Installation
Mobile installation ▼Determine the appropriate angle of the transceiver, using the 3 screw
hole positions on the side of the mounting bracket.
The transceiver may be installed in any position in your car, where the
controls and microphone are easily accessible and it does not interfere
with the safe operation of the vehicle. If your vehicle is equipped with air
bags, be certain your radio will not interfere with their deployment. If you
are uncertain about where to mount the unit, contact your vehicle's dealer.
Caution:
Use only the provided screws to x the
bracket, otherwise it voids warranty and
you risk damaging the circuit board,
components or fall-off of the unit.

2Initial Installation
DC Power Cable Connection
Mobile Operation
The vehicle battery must have a nominal rating of 12V. Never connect
the transceiver to a 24V battery. Be sure to use a 12V vehicle battery
that has sufficient current capacity. If the current to the transceiver is
insufcient, the display may darken during transmission, or transmitting
output power may drop excessively.
1. Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from the
transceiver.
▼Never use the cigarette lighter socket as a DC source.
▼The entire length of the cable must be dressed so it is isolated from
heat, moisture, and the engine secondary(high voltage) ignition
system/cables.
2. After installing cable, in order to avoid the risk of damp, please
use heat-resistant tap to tie together with fuse box. Don't forget to
reinforce whole cable.
3. In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
4. Confirm the correct polarity of the connections, then attach the
power cable to the battery terminals; red connects to the positive (+)
terminal and black connects to the negative (-) terminal.
▼Never remove the fuse holders from the cable.
5. Reconnect any wiring removed from the negative terminal.

Initial Installation
▼Before connecting the DC power 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.
Fixed Station Operation
In order to use this transceiver for xed station operation, you will need
a separate 13.8V DC power supply (not included) , Please contact local
dealer to require.
The current capacity of your power supply must be 20A or more.
Connect the DC power cable to the regulated DC power supply
and ensure that the polarities are correct. (Red: positive, Black:
negative).
▼Never 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.

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 dealer for assistance.
Only use fuses of the specied type and rating, otherwise the transceiver
could be damaged.

If you use the transceiver for a long period when the vehicle battery is
not fully charged, or when the engine is OFF, the battery may become
discharged, and will not have sufcient reserves to start the vehicle. Avoid
using the transceiver in these conditions.
Connect the transceiver’s DC power connector to the connector on
the DC power cable.
▼Press the connectors rmly together until the locking tab clicks.

2Initial Installation
External Speaker
If you plan to use an external speaker, choose a speaker with an
impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")
mono (2-conductor) plug.
After connecting the transceiver to the power supply, the supply voltage
can be displayed on LCD by pressing the
SQL
key together with the
FUNC
key.
The display immediately changes as the voltage supply changes, It also
displays voltage during transmission.
The transceiver will return to its normal operation when the power is
turned ON/OFF or repeat above operation.
Before operating, install an efficient, well-tuned antenna. The success
of your installation will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance 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 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
External speaker adopt double port BTL, please care about the connection.
Do not use the speaker that requires grounding.
The range of displayed voltage is from 7V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more
precise reading is desired.
Power supply voltage Display
Antenna Connection
Accessories Connections
Important
Transmitting without first connecting an antenna or other matched
load may damage the transceiver. Always connect the antenna to the
transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to reduce
the risk of re, electric shock, and transceiver damage.
