1 INSTALLATION
DC POWER CABLE CONNECTION
Connect the DC power cable directly to the vehicleÕs battery terminals using the shortest route. Do not use the cigarette lighter socket! The current rating of the cigarette lighter socket is too small to operate the transceiver. Ensure to use a 12 V vehicle battery which has sufficient current capacity. If the current is insufficient, the display may darken during transmission or the trasceiver may work intermittiently. If you use the transceiver for a long period when the vehicle battery has not been fully charged or when the engine has been stopped, the battery may become discharged in a short time and will not have sufficient reserves to start the engine. Avoid using the transceiver under these conditions. Keep in mind that the
¥Attach the line filter(s) to the DC cable(s) as shown after the installation
Note:
◆Do not use two separate batteries to connect each DC cables from the transceiver
◆Two supplied DC cables (or two optional
ANTENNA CONNECTION
Place the DC cable the wall of the engine compartment securely. Avoid applying excessive heat, vapor and water to the cable.

In general, HF/ 50 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use a strong and rigid mount to safety and securely install the HF/ 50 MHz mobile antenna.
A bumper mount is recommended for stable mounting. However, most recent models of vehicles have plastic bumpers. For such vehicles, ground the antenna mount to the body chassis with a large wire. Antenna installation is critical for successful mobile operation. For further information, refer to The Radio AmateurÕs Handbook, Radio Handbook, or other published texts.
GROUND CONNECTION
The ground, which is the other half of the antenna system, is very important when using a mobile whip type antenna. Connect the feed line ground for the antenna securely to the vehicleÕs chassis, and be certain to bond (electrically connect) the vehicleÕs body to chassis. The sheet metal will provide the primary ground plane, so be sure to establish a good RF connection from the feed line to both the chassis and the body. For comprehensive information on mobile antennas installations and optimization, refer to the ARRL Handbook or similar publications.
IGNITION NOISE
This transceiver has been equipped with a Noise Blanker and Digital Noise Limiter to filter ignition noises out. However, some cars may generate excessive ignition noise. If there is excessive noise, use suppressor spark plugs (with resisters), and/ or DC line filters to reduce the electric noises. The ARRL Handbook, or similar refereneces, has a wealth of information regarding this topic.
Note:
◆After installation and wiring are completed, confirm that all work has been done correctly, then connect the DC power cable plug(s) to the transceiver.
◆If the fuse blows, disconnect the DC power cable plug(s) from the transceiver immediately, then check all the DC power cables to find the reasons of the short circuit. The DC cable may be damaged, short circuited, pinched, or squashed. After resolving the problem, replace the fuse with one of the same type and rating.
◆Do not remove the fuse holder for any reason.
