3.3 Power Connection
Mobile Operation
The vehicle battery must have a nominal rating 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. Your transceiver is
delivery with cigar plug. In case of direct connection with battery :
1. Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from
the transceiver.
• 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.
2. 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.
»Locate the power input connector as close to the transceiver as
possible.
3.2 Intall Microphone Hanger
1. Choose idea location and mark for screw point.
2. Fix the hanger by the srews in accessory list.

3. In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
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.

»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.
3.5 Antenna Connection
3.6 Accessories Connections
Before operating, install an efcient, 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 efciency of
the antenna system and can cause interference to nearby broadcast
television receivers, radio receivers, and other electronic equipment.
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.
