PRECAUTIONS

• Use only in a 12-volt DC negative-ground electrical system.

• Disconnect the vehicle’s negative battery terminal while mounting and connecting the unit.

•

When replacing the fuse, be sure to use one with an identical amperage rating. Using a fuse with a higher amperage rating may cause serious damage to the unit.

• Do NOT attempt to disassemble the unit. Laser beams from the optical pickup are dangerous to the eyes.

• Make sure that pins or other foreign objects do not get inside the unit; they may cause malfunctions, or create safety hazards such as electrical shock or laser-beam exposure.

• When your vehicle has been parked in direct sunlight resulting in a considerable rise in the temperature inside, allow the unit to cool off before operating it.

• Keep the volume at a level at which you can hear outside warning sounds (horns, sirens, etc.).

NOTE

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 circuit

different from that to which the receiver is connected.

– Consult the dealer or an experienced radio/TV

technician for help.

Caution

The use of optical instruments with this product will increase eye hazard.

CAUTION

Modifications or adjustments to this product that are not expressly approved by the manufacturer may void the user’s right or authority to operate this product.

In addition to ordinary CDs, CD-Rs or CD-RWs can be read by this unit. However, NEVER use a CD-R or CD-RW that contains no data or data in the wrong format, such as MP3 or other computer files.

For installation and connections, refer to the separate “INSTALLATION AND CONNECTIONS”.

CD Notes

• Playing a defective or dusty CD can cause dropouts in sound.

• Hold CDs as illustrated.

• Do NOT touch the unlabeled side.

• Do NOT attach any seal, label or data protection sheet to either side of a disc.

• Do NOT expose a CD to direct sunlight or excessive heat.

• Wipe a dirty CD from the center outward with a cleaning cloth. Never use solvents such as benzine or alcohol.

• This unit cannot play 3-inch (8 cm) CDs.

• NEVER insert a 3-inch CD contained in the adapter or any irregularly shaped CD. The unit may not be able to eject it, resulting in a malfunction.
