CB antenna, suitable antenna type and correct installation will provide
excellent communication.
Always use 50 Ohm coaxial cable for a single antenna and 75 Ohm cable for a dual
antenna system. Your antenna system should be 1.5:1 SWR or lower for best
performance. A SWR of 3:1 or higher could damage the transmitter.
1. Screw the antenna connector into the antenna jack.
2. Grounding the antenna system to ensure best performance of this radio.
WARNING:
▲ Always connect the
antenna before transmiting, or it might damage the radio.
▲ To avoid the risk of fire, electric shock, radio damage, all base station should

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.

1. Connect positive red power cable with the + terminal of the battery.
2. Connect negative black power cable with the - terminal of the battery.
3. Connect the DC power cable to the transceiver's power supply connector.
▲ If a cigarette lighter is used, use one rated for at least 10 Amps.
▲ Locate the power cable away from high temperature, moisture, port
re and cable
insulator.
▲ Use a full power cable even it is longer than need, do not take off the fuse holder
from the cable.
