2.2 Licenses 

It is requested by rules that each radio installation site (for 

mobile station or base station) should be provided with a license. 

The license carrier should guarantee that the Tx power, frequency 

and deviation comply with the license requirements. Transmission 

adjustment can only be conducted by license-authorized 

technicians. Installation or operation of the radio does not need a 

license.  

2.3 Check before Installation 

Every radio has been adjusted and checked before shipment.   

Before installation, it’s better to check if the radio’s 

transmission and receiving are normal to make sure its proper 

operation.  

The test should be performed with all cables and accessories 

correctly connected. 

Tx frequency, deviation, power output, Rx sensitivity, squelch, 

audio output, and signaling operation should be checked. 

2.4 Installation

1) Preparation 

Check the vehicle and decide how and where to install the 

radio antenna and accessories. Make sure that the cable will not be 

extruded. And pay attention to the heat dissipation of the radio to 

avoid overheating. 

2) Antenna 

The best position for the antenna is in the center of an open 

and flat conduction region, usually the center of the vehicle roof 

or the cover of the luggage trunk. Connect one end of the earth 

wire to the cover of the luggage trunk and the other end to the car 

outer shell so that the cover of the luggage trunk is grounded.   

3) Connection of Power Cable 

* First of all, please check whether there is a hole for the 

power cable on the insulating board. If no, please bore the board 

with a suitable drill bit and fix a rubber grommet on it to protect 

the cable from abrasion.   

* Afterwards, please pass the cable through the insulating 

board and lead from the car into the engine room. Connect the red 

conductor to the positive terminal of the accumulator and the 

black conductor to the negative terminal.   

* At last, ring the remained conductor and fix it. 

Note:

 Please guarantee sufficient relaxation of the power cable in 

the car so that the radio can be conveniently disassembled, 

assembled, and repaired in the state of power connection.   

4) Installation 

Warning:

 For passenger safety, please install the radio securely 

using the supplied mounting bracket so that the radio will not be 

loosened in case of collision. 

* Take the mounting bracket as the sample to draw the 

position of the four holes for screws. Then drill the holes on the 

instrument panel, and then install the mounting bracket with 4 

M5*16 self-tapping screws. (Note: Please install the radio at a 

position convenient for operation, and leave enough space for 

connection of the cable.)   

* Slide the radio into the mounting bracket and fix it to the 

bracket with 4 M4*10 SEMS screws (with flat washer and spring 

washer). (Set an appropriate height and angle for the radio by 

using different screw holes of the bracket.) 

* Connect the antenna and the power cable to the radio. 

* Install the microphone hanger at an appropriate position 

using 2 M4*16 self-tapping screws. (It should be made sure that 

the microphone and its cable will not affect safe driving.)   

* Connect the microphone to the MIC jack on the front panel 

of the radio and put the microphone on the hanger. 

Note:

 When replacing the fuse of the power cable, only use fuses 

of the same type and rating; otherwise the radio could be 

damaged. 

5) Attention 

If you have no plan to use external speaker, please cover the 

speaker jack with the supplied rubber plug to prevent dust and 

sand getting in.
