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

Note: 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 the cable, to avoid the risk of damp, please use a heat-resistant tap to tie together with the fuse box. Don’t forget to reinforce the whole cable.
3. In order to avoid the risk of a short circuit, please cut down the connection with the negative (-) of the battery, then connect to the 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 longer than 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

In order to use this transceiver for fixed station operation, you will need a separate 13.8V DC power supply (not included), power supply as an optional accessory. Please contact the local dealer to request.
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.

NOTE: 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 authorizeddealer or an authorizedservice center for assistance.

Only use fuses of the specified type and rating, otherwise, the transceiver could be damaged.

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

NOTE:

• 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 the antenna on a car are shown as follows:

Accessories Connections

External Speaker

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

Note: External speakers adopt double-port BTL. Please care about the connection way. The speaker can not connect with the ground. Otherwise, the speaker will be at 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 firmly on the plug until the locking tab clicks.

DISPLAY MODE

LCD display mode.

• A. Frequency+Channel mode: When set to display as “FRQ”, it enters into Frequency+Channel mode, where new settings of channel operation and shortcut operation can be temporarily used by the user. Once the radio is turned off or switched to another channel, the temporary setting will be erased and back to the initial settings.(As pic 1)
• B. Channel+Name Tag Mode: When set to display as “NM”,it enters into Channel +Name Tag mode. At this mode, it will display the corresponding channel name when the current channel is edited with a name. Otherwise, it will display frequency + channel. Its operations are the same as frequency + channel mode.(As pic 2)
• C. VFO Mode(Frequency mode): This mode shows only frequency on the display. Shortcut operation and Channel setting will be changed & stored as the latest value permanently. Once the radio is turned off or changed to a new VFO frequency, the latest setting remains until the next change.(As pic 3)

4. According to instructions, select the correct”COM Port”, then click “OK” to start the programming software.

Note: Even on the same computer. The selective COM Port is different when USB cable connects with a different USB port.

You shall install the software before connecting the USB cable. Switch on the transceiver before writing the frequency. You had better not switch on or off the power supply of the transceiver when it is connected to the computer, otherwise, it will make the transceiver unable to read or write frequency. In this case, you have to turn off the programming software, pull out the USB cable. Then reinsert the USB cable and open the software, then rechoose the COM Port, it will turn into normal operation. Therefore, please connect the transceiver to the computer after switching on the transceiver. Don’t restart the transceiver power when it is connected to the computer.

‘When programming the radio, read the factory initial data first, then rewrite the frequency and signaling, etc., otherwise errors may occur because of different frequency bands etc. You can choose the preset power, Rx / Tx Band, bandwidth, etc.
