Fuse Location

Transceiver

Supplied Accessory DC

power cable

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 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 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 broadcast television

receivers, radio receivers, and other electronic equipment.

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.

Initial Installation

The possible locations of antenna on a car are shown as following:

External Speaker

If you plan to use an external speaker, choose a speaker with an

impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")

mono (2-conductor) plug.

SP-01

External speaker adopt double port BTL, please care about the connecting

way. The speaker can not connect with the ground, otherwise the speaker

will be fault. The wrong connecting way as the following picture.
