INITIAL INSTALLATION
1. 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 (2pcs) and
flat washers (2pcs).
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.
2. Intall Microphone Hanger
1) Choose idea location and mark for screw point.
1) Fix the hanger by the srews in accessory list.
3. Power Connection
» Locate the power input connector as close to the transceiver as possible.
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 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 termin-
als 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.
• The entire length of the cable must be dressed so it is isolated from heat, moisture, and the

Fuse Replacement
This radio adopt 5A, 250V fuse.
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 Retevis dealer or an authorized Retevis servicecenter for assistance.
1) Open the fuse holder
2) Replace the fuse and screw on the holder.
Only use fuses of the specified 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 charg-
ed, or when the engine is OFF, the battery may become discharged, and will not have
sufficient reserves to start the vehicle. Avoid using the transceiver in these conditions.
Antenna Connection
Before operating, install an efficient, well-tuned antenna. The success of your installation will de-
pend 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 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
feedlines 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.
