3. INITIAL INSTALLATION
To install the transceiver, select a safe, convenient location inside your vehicle that
minimizes danger to your passengers and yourself while the vehicle is in motion. Consider
installing the unit at an appropriate position so that knees or legs will not strike it during
sudden braking of your vehicle. Try to pick a well ventilated location that is shielded from
direct sunlight.
1.Install the mounting bracket in the vehicle using the supplied selftapping screws (2pcs)
DQGÀDWZDVKHUVSFV2.Position the transceiver, then insert and tighten the supplied hexagon SEMS screws.
ƇDouble check that all screws are tightened to prevent vehicle vibration from loosening
the bracket or transceiver.

contact local dealer to require.
The recommended current capacity of your power supply is 12A.
1.Connect the DC power cable to the regulated DC power supply and ensure that the
polarities are correct. (Red: positive, Black: negative).
ƇDo not directly connect the transceiver to an AC outlet.
ƇUse the supplied DC power cable to connect the transceiver to a regulated power
supply.
ƇDo not substitute a cable with smaller gauge wires.1.Route the DC power cable supplied with the transceiver directly to the vehicle's battery
terminals using the shortest path from the transceiver.
ƇWe recommend you do not use the cigarette lighter socket as some cigarette lighter
sockets introduce an unacceptable voltage drop.
ƇThe entire length of the cable must be dressed so it is isolated from heat, moisture,
and the 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.

battery terminals; red connects to the positive (+) terminal and black connects to the
negative (-) terminal.
ƇUse 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.
