The current capacity of your power supply must be 12A or more.

Connect the DC power cable to the regulated DC power supply and

ensure that the polarities are correct. (Red: positive, Black: negative).

Never 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.

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 dealer for

assistance.

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 transceiver in these conditions.

Antenna Connection

Before operating, install an efficient, well-tuned antenna. The success

of your installation will depend on the type of antenna and its correct

installation.

Use a 50Ω impedance antenna and low-loss coaxial feed-line that

has a characteristic impedance of 50Ω, to match the transceiver input

impedance. Coupling the antenna to the transceiver via feed-lines having

an impedance other than 50Ω reduces the efficiency of the antenna

system and can cause interference to nearby electronic equipment.
