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.
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.

6) Connect the DC power cable to the transceiver's power supply connector.
• Press the connectors firmly together until the locking tab clicks.

Fixed Station Operation
In order to use this transceiver for fixed station operation, you will need a separate 13.8V DC
power supply (not included), power supply( QRP-01) as optional accessories. Please contact
local dealer to require.
The recommended current capacity of your power supply is 10A.
1) Connect the DC power cable to the regulated DC power supply and ensure that the polarities
are correct. (Red: positive, Black: negative).
• Do not directly connect the transceiver to an AC outlet.
• Use the supplied DC power cable to connect the transceiver to a regulated power supply.
• Do not substitute a cable with smaller gauge wires.

2) Connect the transceiver's DC power connector to the connector on the DC power cable.
» Press the connectors firmly together until the locking tab clicks.
» Before connecting the DC power to the transceiver, be sure to switch the transceiver
and the DC power supply OFF.
» Do not plug the DC power supply into an AC outlet until you make all connections.
Fuse Replacement
This radio adopt 5A, 250V fuse.
If the fuse blows, determine the cause, then correct the problem. After the problem is resolved,
replace the fuse. If newly installed fuses continue to blow, disconnect the power cable and
contact your authorized Retevis dealer or an authorized Retevis servicecenter for assistance.
1) Open the fuse holder

Only use fuses of the specified type and rating, otherwise the transceiver could be damaged.
» If you use the transceiver for a long period when the vehicle battery is not fully charg-
ed, or when the engine is OFF, the battery may become discharged, and will not have
sufficient reserves to start the vehicle. Avoid using the transceiver in these conditions.

Antenna Connection

Before operating, install an efficient, well-tuned antenna. The success of your installation will de-
pend 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
feedlines having an impedance other than 50Ω reduces the efficiency of the antenna system and
can cause interference to nearby broadcast television receivers, radio receivers, and other
electronic equipment.
