  • The disc name preset function can register names of up to 100 discs using up to 12 characters for each disc name.
  • The availability of this function as well as the number of discs which can be registered using this function and the number of usable characters may be variable depending on the control unit in use.

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.


  • Be sure to use CDs with disc mark diSE ELSE CISt only for this unit.
  • 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 CDs recorded on CD-R or CD-RW.

Do Not Use CDs with Sticker on the Labeled Side

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

Cleaning the unit

  • If the front panel is dirty, wipe it clean with a silicon cloth or soft dry cloth with the power off.


Do not use hard cloths or paint thinner, alcohol,  or other volatile solvents. These may damage external surfaces or remove indicator characters.

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.

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.

Handling compact discs

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.
  • If you do not use your unit for an extended time, remove the discs from the unit and put them in their cases. Do not leave them lying around without cases, piled up, or leaning on a wall and so on.
  • If you attach an adapter to an 8 cm (3″) compact disc and load it into this unit, the adapter may be detached from the disc, causing damage to the unit. Do not use 8 cm (3) compact discs.

  • Take care to insert trays into the correct grooves in the disc magazine and to insert discs properly into the tray grooves. Otherwise malfunction may occur or the disc may be damaged.
  • Insert all trays even when some of them do not carry discs. Otherwise malfunction or operation failure may occur.
  • 8-cm discs cannot be used. If an 8-cm disc adapter is used, the disc cannot be ejected.
