The following illustration shows a typical installation. However, you should make adjustments corresponding to your specific car. If you have any questions or require information regarding installation kits, consult your "JVC IN-CAR ENTERTAINMENT" car audio dealer or a company supplying kits.
When making the terminal connections...
Properly fix the terminal with the screw provided by turning it in the direction as illustrated.
Note
When you tighten the screw, make sure that the screw is securely fi xed in place to prevent disconnection of the terminal. Avoid over-tightening as it may cause damage to the screw or its head slot.
To prevent short circuits while making connections, keep the battery's negative terminal disconnected.
The lead wire connected to the + B terminal of this unit should have a cross-section of more than 5 mm2. Be sure to use a ring terminal (optional) for secure connection.
When connecting a unit without a remote lead (a), connect to the accessory circuit of the car which is activated by the ignition switch. In this case, noise may occur when the car receiver is turned on or off. To avoid this noise, do not turn on or off the car receiver itself. You can turn on or off the car receiver along with the on/off operation of the ignition switch.
If you use JVC car receiver with a remote lead (b), connect to the REM terminal on this unit.
