Kenwood KVT-920DVD instruction manual Cleaning the disc slot

Cleaning the disc slot

As dust can accumulate in the disc slot, clean it occasionally. Your discs can get scratched if you put them in a dusty disc slot.

Lens Fogging

Right after you turn on the car heater in cold weather, dew or condensation may form on the lens in the disc player of the unit. Called lens fogging, discs may be impossible to play. In such a situation, remove the disc and wait for the condensation to evaporate. If the unit still does not operate normally after a whilst, consult your Kenwood dealer.

Playing a disc that is dirty, scratched or warped can cause the sound to skip and the unit to operate incorrectly, resulting in worsened sound quality. Take the following precautions to prevent your discs from getting scratched or damaged.

Handling discs

•Do not touch the recorded side of the disc (i.e., the side opposite the label) when holding it.

•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 tape on either side of the disc.

Checking New discs for Burrs

When playing a new disc for the first time, check that there are not any burrs stuck to the perimeter of the disc or in the central hole. discs with burrs stuck on them may not load properly or may skip whilst playing. Remove burrs using a ballpoint pen or a similar utensil.

Do Not Load CD Accessories in Slot

Do not use commercially available CD accessories that can be loaded into the CD slot, such as stabilisers, protective sheets, or CD cleaning discs, since they can cause the unit to malfunction.

Removing the disc

Only remove the disc from the machine in a horizontal direction. You may damage the surface of the disc if you try pulling it down as it ejects.

Do Not Use Special Shape Discs

•Be sure to use round shape Discs only for this unit and do not use any special shape Discs. Use of special shape Discs may cause the unit to malfunction.

•CD-Rs and CD-RWs which have not undergone finalization processing cannot be played. (For more information on finalization processing, refer to the manual for your CD-R/CD-RW writing software or CD- R/CD-RW recorder.) Additionally, depending on the recording status, it may prove impossible to play certain Discs recorded on CD-R or CD-RW.

Storing discs

•Do not store discs in areas exposed to direct sunlight (such as a car seat or the dashboard) or other hot places. 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.

•Remove discs from the unit when not listening to them for a while, and put them back in their cases. Do not pile up discs that are removed from their cases or prop them against something.

Cleaning discs

If a disc has become dirty, wipe it off gently using a commercially available cleaning cloth or a soft cotton cloth, starting from the centre of the disc and moving outward. Do not clean discs with conventional record cleaners, anti- static formulas, or chemicals such as paint thinner or benzene.

Do Not Use discs with Sticker on the Labelled Side

Do not use the disc with the label sticker stuck on it. Using such a disc may cause the disc to be deformed and the sticker to peel off, resulting in malfunction of the unit.
