vehicle battery terminal in a shortest route.
It is suggested not to use a cigar lighter socket as much as possible as some of them
may lead to great voltage drop.
The whole power line must be packed so as to isolate it from heat and moisture and
from the generator ignition system/connection line.
2. When the power line is installed in place, wind the fuse holder with heat-resistant adhesive
tape to protect it against moisture. It’s better to use heat-resistant adhesive tape to wrap the
whole power line.
3. To prevent short-circuit, disconnect the other connection lines at the negative (-) battery
terminal before connecting the talkie walkie.
4. Please first confirm the polarity of connection is correct, and then connect the power line
to the battery terminal. Connect the red wire to the positive (+) terminal of battery and the
black wire to the negative (-) terminal of battery.
Use the whole power line and do not cut the surplus part even if it is longer than
required. Be sure to remember: never remove the fuse holder from the power line.
5. Reconnect all connection lines that have been disconnected from the negative terminal
previously.
6. Connect the DC power line to the walkie talkie.
Press them together with force till the locating plate is locked with a sound of
“click”.
Operation of fixed radio station
If you intend to use the talkie walkie as a fixed radio station, you need to buy a independent
type of 13.8 DC power supply separately with a suggested continuous current capacity of
above 12A.
Note:
Do not connect this DC power supply to the AC power socket before all connections are
completed. (Do not connect the talkie walkie with power on.)
Please connect all lines and finally insert the DC power supply device into the AC
socket.
1. Be sure the talkie walkie and the DC power supply are off.
2. Connect the DC power supply line to the DC regulated power supply and make sure the
polarities are correct (red: positive, black: negative).
Never directly connect the talkie walkie to theAC socket.
Use the DC power line attached to connect the talkie walkie to the DC regulated
power supply.
Never use a power line with the specification and parameters lower than the
original one to replace the original power line.
3. Connect the DC power line to the talkie walkie.
Press them together with force till the locating plate is locked with a sound of
“click”.
Fuse replacement

Use the fuse of designated type and rated value. Otherwise, the talkie walkie may be
damaged at your own risk.
Connection of Antenna
Before using the talkie walkie, you must install a high efficiency and fine tuned antenna.
Successful installation depends on the correct antenna type and installation. If a proper
antenna system is selected and installed correctly, the talkie walkie will achieve best
performance.
Use an antenna with a characteristic impedance of 50Ω and a low loss coaxial feeder
also with 50Ω characteristic impedance to match the input impedance of the talkie walkie.
Using a feeder with an impedance of other than 50Ω to connect the antenna with the talkie
walkie will reduce the performance of the antenna system, may cause interference to the
nearby radio and TV receivers, radio receivers and other electronic devices and even damage
the talkie walkie.
Without the connection with antenna or other matched load, it is prohibited to use
the talkie walkie to transmit. Otherwise, the talkie walkie will be damaged. Be sure
to connect the antenna to the talkie walkie before transmission, and only when the
connection is confirmed can the transmission be made.
All fixed radio stations must be furnished with a lightning arrester to reduce the
risk of the damage of talkie walkie by fire or electric shock.
The location and fixed mode of the antenna on the vehicle are shown as follows:
