3.1 Antenna Installation

Before using this radio, please install an efficient and resonant antenna. Using an antenna that is correctly installed and tuned will enable excellent communication performance.

This radio requires an antenna impedance of 50 ohms, unbalanced.

1. Screw the antenna connector into the antenna jack.
2. Grounding of the antenna system is recommended to ensure best performance.

WARNING:

• NEVER transmit without a connected resonant antenna, or a suitable 50 ohm load being connected. Damage to the radio may result.
• To reduce the risk of electric shock, or radio damage, base station installations should include lightning protection devices.
• Ask your authorized dealer or an authorized service center for available antenna options.

3.2 Power Connection

This radio requires a 13.8V (12V) DC power supply. Never connect the radio directly to a 24V DC battery system, as can be found in some vehicles. Please refer to the radio Specifications to ensure your 13.8V DC power supply can provide enough current (amps), otherwise poor performance may occur.

1. Connect the positive (red) power cable to the + terminal of the battery.
2. Connect the negative (black) power cable to the - terminal of the battery.

Locate the power cable away from high temperature, moisture, and other electrical systems. Ensure it is installed where it cannot be damaged.

It is not recommended to use a vehicle cigar/cigarette lighter socket to power the radio, as it may not supply the correct voltage or current.

Do not remove the fuse holder from the cable.

3.3 Replacing Fuse

This radio requires a 15A, 250V fuse.

If the fuse blows, determine the reason, 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 service center.

1. Pull the two fuse cover in opposite directions and open it.
2. Replace the blown fuse with a new one, and close the fuse holder.
3. Be sure to only use the correct fuse type, otherwise damage may occur.

3.4 Install Microphone Hanger

Choose a location which will not interfere with the driver. Use the supplied self-tapping screws and pads to install the hanger.

3.5 Install External Speaker

If using an external speaker, please choose an 8 ohm speaker with a 3.5mm mono (double cable) TS type plug.

1. Locate the external speaker in a suitable place.
2. Plug into the speaker jack.
