1. Install the mounting bracket in the vehicle using the supplied
self-tapping screws (4pcs) and at washers (4pcs).
2. Position the transceiver, then insert and tighten the supplied hexa-
gon 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
otherwise 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 13.8V. Never
connect the transceiver to a 24V battery. Be sure to use a 13.8V
vehicle battery that has sufficient current capacity. If the current
to the transceiver is insufficient, 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 rein-
force whole cable.
3. In order to avoid the risk of short circuit, please cut down connec-
tion 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.
6. Connect the DC power cable to the transceiver's power supply con-
nector.
▼Press the connectors rmly together until the locking tab clicks.

Initial Installation
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.
Fuse Location Fuse Current Rating
Transceiver 15A
Supplied Accessory DC
power cable 20A
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.

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 / REV key together with
the [SQL / REV] 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.

Antenna Connection
Accessories Connections
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.
