ANTENNA INSTALLATION
Before usin g this radi o, please instal l a high efficent and harm on ious ad justed
CB antenna, s ui ta bl e antenna type a nd correct installation will bring ex ce ll en t
communication.
To match with the radio, the antenna and cable shall with characteristic impedance of
50ohm, or the antenna system will not efcient enough and will disturb TV, radio or other
electronics.
Screw the antenna connector into the antenna jack.1.
Grounding the antenna system to ensure best performance of this radio.2.
WARNING:
▲ Connect antenna rstly before transmiting, or it might damage the radio.

equip of lightning protector
▲ Be sure choose a matching antenna, you may enquiry our dealers.
The position of antenna can be put as following example:3.
POWER CONNECTION
This radio adopt 13.8V power supply, never connect it to 24V battery, And the 13.8V car
battery shall with sufcient current, or the LCD will become dark and Transmit power
will drop down.
Connect positive red power cable with the + terminal of the battery.1.
Connect negative black power cable with the - terminal of the battery.2.
Connect the DC power cable to the transceiver's power supply connector.3.
▲ We suggest not use cigar lighter as it often bring down the voltage.
▲ Locate the power cable away from high temperature, moisture, portre and cable
insulator.
▲ Use a full power cable even it is longer than need, do not take off the fuse holder
from the cable.
