The marking of products using lasers (Except for some areas) COMPACT DISC AUTO CHANGER

Do Not Use Special Shape CDs
� Be sure to use round shape CDs only for this unit and do not use any special shape CDs. Use of special shape CDs may cause the unit to malfunction.

Stains, scratches, or warping can cause skipping, malfunction, or low sound quality. Take the following precautions to avoid damage to the compact discs.
� Avoid touching the recorded side (the side without the titles on) when you hold a compact disc. � The reflective film on a CD-R or a CD-RW is more fragile than that on an ordinary music CD, and may peel off if scratched. Fingerprints on a CD-R or CD-RW are also more likely to cause skipping when the disc is played. For these reasons, handle the disc very carefully. Detailed handling instructions will appear on the CD-R or CD-RW package: read this information carefully before using the disc. � Do not stick paper tape, etc. on either stick of the disc. � Do not store discs where they will be exposed to direct sunlight (such as on the seat and dashboard) or high heat. A CD-R or CD-RW is more susceptible than a music CD to damage from high temperatures and humidity, and in some cases, may become unusable if left in the car for long periods of time.

When removing the CD changer, be sure to first eject a magazine then unplug the changer cord. Do not forget to attach the transport screws before transporting the CD changer. The CD changer may be damaged during transport if a magazine or CD is left inside it or the transport screws are not attached.

Lens fogging
In cold climates, there may be a period after you turn on your vehicle's heater when the lens that guides the laser beam used in your CD player fogs up. If this happens, you cannot play compact discs. Take out discs and the fogging will disappear. If it does not return to normal after several hours, contact your Kenwood dealer.

NOTE
� If you have difficulty in installing this unit in your vehicle, contact your Kenwood dealer. � If it doesn't seem to be working properly, first press the Reset button. If the malfunction persists, consult your Kenwood dealer.

Heat protection
In warm climates, when vehicles are left standing in direct sunlight with the windows closed, the temperature inside can rise above 60°C. The unit's protection circuits will then display the message "HOLD" and prevent the player from operating. Just open the windows or turn on the air conditioning. As soon as the "HOLD" message disappears, the player will operate normally.

2CAUTION � Do not connect the changer control cable while the control unit is turned ON. � Be sure to press the reset button after installation. � Do not install an antenna of radio equipment or distribute the antenna cable near the changer output cable, for this could cause malfunction with this unit.
