DC Power Cable with Fuse Holder

Mobile installation



The radio may be installed in any position in your car, where the controls and microphone are easily accessible and it does not interfere with the safe operation of the vehicle. If your vehicle is equipped with air bags, be certain your radio will not interfere with their deployment. If you are uncertain about where to mount the unit, contact your vehicle's dealer.

Install the mounting bracket in the vehicle using the supplied

self-tapping screws (4pcs) and at washers (4pcs).

Initial Installation

▼

Determine the appropriate angle of the transceiver, using the 3 screw hole positions on the side of the mounting bracket.

Position the radio , then insert and tighten the supplied

gon SEMS screws.

▼

Double check that all screws are tightened to prevent vehicle vibration from loosening the bracket or transceiver.

Caution:

Use only the provided screws otherwise you risk damaging the circuit board, components or fall-off of the unit.

DC Power Cable Connection



Initial Installation

Mobile Operation

The vehicle battery must have a nominal rating of 13.8V. Never connect the radio to a 24V battery. Be sure to use a 13.8V vehicle battery that has sufficient current capacity. If the current to the radio is insufficient, the display may darken during transmission, or transmitting output power may drop excessively.

Route the DC power cable supplied with the radio directly

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

▼

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 order to avoid the risk of short circuit, please cut down connec-

tion with negative (-) of battery, then connect with radio.

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.

▼

Never remove the fuse holders from the cable.

Reconnect any wiring removed from the negative terminal.

Connect the DC power cable to the radio's power supply

nector.

▼

Press the connectors rmly 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 dealer for assistance

Only use fuses of the specied type and rating, otherwise the radio

could be damaged.

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.

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 radio input

impedance. Coupling the antenna to the radio 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.

External speaker adopt double port BTL, please care about the connection. Do not use the speaker that requires grounding.

Microphone

For voice communications, connect a provided microphone into the socket on the front of the main unit. Turn the ring firmly on the plug until it locks. Attach the supplied microphone hanger in an appropriate location using the screws included in the screw set.
