Initial Installation
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.
111Install the mounting bracket in the vehicle using the supplied selftapping screws (4pcs) and flat washers (4pcs).
 Determine the appropriate angle of the transceiver, using the 3 screw
hole positions on the side of the mounting bracket.
DC Power Cable Connection

Mounting bracket
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 insufficient, the display may darken during
transmission, or transmitting output power may drop excessively.
111Route the DC power cable supplied with the transceiver directly 2
to the vehicle's battery terminals using the shortest path from the
transceiver.
 We recommend you do not use the cigarette lighter socket as some
cigarette lighter sockets introduce an unacceptable voltage drop.
222Position 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.

 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.
222After 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.
333In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
444Confirm 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.

Fixed Station Operation
In order to use this transceiver for fixed station operation, you will
need a separate 13.8V DC power supply (not included), power
supply( QRP-01) as optional accessories. Please contact local dealer
to require.
The recommended current capacity of your power supply is 12A.
REPLACING FUSES
The EUT can be used on the vehicle.
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 autho-rized
Mobile Radio dealer or an authorized Mobile Radio servi-cecenter for
assistance.
Initial Installation

impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")
mono (2-conductor) plug.
SP-01
Antenna Connection
External speaker adopt double port BTL, please care about the connecting
way. The speaker can not connect with the ground, otherwise the speaker
will be fault. The wrong connecting way as the following picture.

SP
SP-01
REPT
Transmitting without first connecting an antenna or other matched
load may damage the transceiver. Always connect the antenna to the
transceiver before transmitting.
All fixed stations should be equipped with a lightning arrester to reduce
the risk of fire, electric shock, and transceiver damage.
SP
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 broadcast television
receivers, radio receivers, and other electronic equipment.
REPT
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.
