3. To prevent the risk of short circuits, disconnect other wiring form the negative (-) battery terminal
before connecting the transceiver.
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.
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 service center for assistance.
CAUTION
Only use fuses of the specified type and rating; otherwise the transceiver could be damaged.
Antenna Connection
Before operation, 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 Ohm impedance antenna and low-loss coaxial feed line that has a characteristic impedance
of 50 Ohm, to match the transceiver input impedance.
Coupling the antenna to the transceiver via feed lines having an impedance other than 50 Ohm reduces
the efficiency of the antenna system and can cause interference to nearby broadcast television
receivers, radio receivers, and other electronic equipment.
CAUTION
• 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.
