INFORMATION (For U.S.A.)

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced radio/TV technician for help.

Caution

Changes or modifications not approved by JVC could void the user’s authority to operate the equipment.

For safety....

• Do not raise the volume level too much, as this will block outside sounds, making driving dangerous.

CAUTIONS AND NOTES

This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems.

• To prevent short circuits, we recommend that you disconnect the battery’s negative terminal and make all electrical connections before installing the unit.

• Cover the unused terminals with insulating tape to prevent them from short circuiting.

• When an extension lead is used, it should be as thick and short as possible; connect it firmly with

insulating tape.

• Be sure to leave an appropriate space between the antenna and the wires of this unit.

• When replacing the fuse, only use a 15 A fuse.

• Do not let foreign objects get inside the unit.

• To keep the heat dissipation mechanism running effectively, wipe the accumulated dust off

periodically.

• Using this subwoofer system with the volume on loud for a long period of time will exhaust the battery, while the engine is turned off or while the engine is idling.

• This unit becomes very hot. Be careful not to touch the unit not only when using but for a while after using.

DO NOT disassemble the units since there are no user serviceable parts inside.
