Preparation for operating the radio
Radio installation
For sake of your own and passengers’ safeties, please find a safe and
convenient position in order to prevent the damage caused by moving car. -
You can consider installing the radio in front of the front passenger seat
below the panel section or the car trunk. This will prevent your knees and
legs crashing the radio in emergency brake. You should install it with good
ventilation and avoiding the direct sunlight
1. Install the mounting bracket to the car with using the self-taping
screws and flat washers (2 pcs screws each kind).
•Screws can be put upside down (under the dashboard mounting) or upwards
the mounting bracket.
•When installing the mounting bracket, please make sure the screw side
edge with slots on the bracket are backwards.
2. Fixed the radio and then insert the equipped with six angles combination
screw and flat washers (each equipped with 2 sides and each side of 1 screw
set) and tighten them.
• Please make sure all the screws are tightened to prevent the stent and
radio loosing caused by car vibration.
• With the rotatable fixed point on the left and right sides of the vehicle
rear bracket, the rotating bracket can tilt the main body at an appropriate
angle.
Connecting Cable Power
■ Radio Operation
Make sure to use 12V car batteries. If the radio's power is not enough
during transmitting the screen will grow dark and the output power may
be significantly decreased. Please do not connect the radio to the 24V
power battery.
Note: If the battery is not fully charged or when the engine is switched
off, but the battery is still not fully charged, the battery may discharge
and there will not be enough power to start the car. In this case, please
avoid using the radio in following situation:
1. Use the radio with the DC power cord to directly connect to the car
battery and radio within shortest area.
Flat washers
Self-tapping screws
(5X16mm)

• If you use a noise filter, the metal parts of the car shall be fitted
with an insulator to prevent it from touching the car.
• We do not recommend you use the cigarette lighter socket because some
of the cigarette lighter socket will cause big substantial voltage.
•If you have to connect the power cord through a car chassis or a hole
on the car (such as a firewall in front of the passenger compartment),
please use the rubber ring to prevent the power cord and remove the fuse
holder to pass the power cord through the firewall.
• The entire power cord must be wrapped in order to keep the heat
insulated and insulation from the engine (high pressure) system.
2. After the power cord is already installed, wrap around the fuse
holder to make it moisture-proof, including the whole power cord.
3. Please cut off all wire connections on the negative battery terminal
before connecting the radio to prevent the short circuit.
4. To confirm the connection is correct then connect the power cord to
the power supply; red connection to the positive (+), black connection to
the negative (-)
•To use the whole power line, please do not cut off excessive parts of
power line even if it is longer than desired length. Remember, do not
remove the fuse holder from the power cord.
5. Reconnect all wiring connections that were previously disconnected on
the negative terminal.
6. Connect the DC power supply to radio.
• Connect the plug into the socket until you hear a click sound.
■ Base Station Operation
To use it as a base station, you need a separate 13.8V DC power supply.
This power supply is recommended for current capacity above 12A.
Note: Do not connect the DC power to the AC power socket before completing
all connections.
1. Make sure that both radios and DC power are off.
2. Connect the DC power supply to the regulated DC power supply and make
sure that the polarity is correct. (Red: positive, black: negative).
•Use the DC power cord to connect the radio to the regulated power
supply. Don't connect the radio directly to the AC power socket.
• Do not use the smaller size of the power cord to make a replacement.
3. Connect the DC power cord to the radio.
• Connect and press the socket together until you hear a click sound.
Fuse holder (E type)
4
Replace fuse
If the fuse is blown, please find out the cause and then solve the problem.
After the problem is fixed then replace the fuse. But if after re-
installation the fuse is still blown, please disconnect the power cord and
contact the local authorized dealer or authorized service center for
assistance.
Fuse position
Fuse rated current
Radio (in DC connector) 10A
Equipped with DC power cord 10A
Note: Please useonly the specified type and the rated value
of the fuse; otherwise, it might damage the radio.
If the transmission impedance of the feeder line is less than 500 the
antenna connection will reduce the effectiveness of the antenna system
and will cause interference to the nearby radio and television
receivers, radio receivers and other electronic devices, and even damage
the radio.
Note:
•If transmitting without an antenna or other matched load line, it could
damage the radio. The antenna must connect to the radio before transmitting
•All base stations should be equipped with lightning arrester to reduce
the risk of fire, electric shock or radio damage.
Antenna connection
Before operation, you must first install and adjust well the antenna.
Success installation depends mainly on the antenna type and a correct
installation. The radio will have best performance if the appropriate
antenna is properly installed. A low loss coaxial feeder line with 500
impedance is used to match the input impedance of the radio.

The left side of the walkie-talkie has two jacks for SP and MIC. Please
refer to the instructions to determine how to use an external speaker or
headset + MIC accessory.
■ Microphone
Please insert the provided speaker microphone (with built-in speaker) to
the RJ45 jack on left side of the radio to make voice communication. Press
the connector until you hear a click sound from the locating plate in place.
