DC Power Cable Connection

Mobile Operation

The v ehicle batter y must have a nominal ra ting of 12V. Never connect the transceiver to a 24V battery. Be sure to use a 12V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmitting output power may drop excessively.

Route the DC power cable supplied with the transceiver directly

to the vehicle's battery terminals using the shortest path from the transceiver.

Never use the cigarette lighter socket as a DC source.



The entire length of the cable must be dressed so it is isolated from



heat, moisture, and the engine secondary (high voltage) ignition system/cables.

After installing cable, in order to avoid the risk of damp, please

use heat-resistant tap to tie together with fuse box. Don't forget to reinforce whole cable.

In or der to av oid th e r isk of sh ort ci rcu it, pl eas e c ut dow n

precise reading is desired.

Initial Installation

Accessories Connections

External Speaker

If you plan to use the op tional external s peaker/s, There are 2 options. For a single speaker, plug into the 3.5mm SP Jack on the rear of the radio to hear both bands through one speaker. To use dual speakers, use the stereo plug it into the 3.5mm ST Jack on the rear of the radio to split the left and right bands between the 2 speakers.

External speaker

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 lo w-los s 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 televisions, 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 xed stations should be equipped with a lightning arrester to reduce the risk of re, electric shock, and transceiver damage.

Microphone

For voice communications, connect a provided microphone into the

socket on the front of the main unit. Turn the ring rmly on the plug

until it locks. Attach the supplied microphone hanger in an appropriate location using the screws included in the screw set.

After installing your antenna, ensure that you have the best possible SWR reading.

IMPORTANT: RF Hazard Warning

The electro-magnetic exposure of this device may exceed the European standards of the hazard level when transmitting at the high-power setting while connected to a unity gain antenna at a distance of 63cm or less from the operator. Furthermore, the hazardous RF exposure level depends on the conditions of the combination of the antenna gain, distance from the operator, output setting and installation environment, the refore the operator m ay be exposed to stronger RF even at a distance of more than 63cm. For safety purpose, it is recommended that the antenna be installed outside of, and as far as possible from, the operator’s area. Avoid using an excessively high-gained antenna in case the distance between the operator and the antenna is very limited. Always use the minimum necessary output power for communications.

External single speaker (3.5mm Mono Out)
