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.

1. Install the mounting bracket in the vehicle using the supplied selftapping 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.

DC Power Cable 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 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.
   • 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.
   • Use the full length of the cable without cutting off excess even if the cable is longerthan required. In particular, 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 connector.
   • Press the connectors firmly together until the locking tab clicks.

Fixed Station Operation
DC power supply, Please contact local dealer to require. The recommended current capacity of your power supply is 12A.

1. Connect the DC power cable to the regulated DC power supply and ensure that the polarities are correct. (Red: positive, Black: negative).
   • Do not 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.
     
2. Connect the transceiver's DC power connector to the connector on the DC power cable.
   • Press the connectors firmly together until the locking tab clicks.

• 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.

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 authorized dealer or an authorized servicecenter for assistance.

Fuse Location	Fuse Current Rating
Transceiver 10A	10A
Supplied Accessory DC power cable	10A

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 charged, or when the engine is OFF, the battery may become discharged, and will not have sufficient reserves to start the vehicle. Avoid using the transeceiver in these conditions.

Antenna Connection

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. Use a 50 impedance antenna and low-loss coaxial feed-line that has a characteristic impdeance of 50,to match the transceiver input impedance, Coupling the antenna to the transceiver via feed-lines having an impedance other than 50 reduces the efficiency of the antenna system and can cause interference to nearby broadcast television receivers, radio receivers, and other electronic equipment.

• 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.

The possible locations of antenna on a car are shown as following:

Accessories Connections

External Speaker
If you plan to use an external speaker, choose a speaker with an impedance of 8.The external speaker jack accepts a 3.5mm (1/8") mono (2-conductor) plug.

• 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.
  

Microphone
For voice communications, connect a microphone equipped with an 8-pin modular plug into the modular socket on the front of the main unit. Press irmly on the plug until the locking tab clicks.
