Additional Information
Precautions
•If your car has been parked in direct sunlight, allow the unit to cool off before operating it.
•Power antenna (aerial) will extend automatically while the unit is operating.
Moisture condensation
On a rainy day or in a very damp area, moisture condensation may occur inside the lenses and display of the unit. Should this occur, the unit will not operate properly. In such a case, remove the disc and wait for about an hour until the moisture has evaporated.
To maintain high sound quality
Be careful not to splash juice or other soft drinks onto the unit or discs.
Notes on discs
•To keep a disc clean, do not touch its surface. Handle the disc by its edge.
•Keep your discs in their cases or disc magazines when not in use.
•Do not subject discs to heat/high temperature. Avoid leaving them in a parked car or on a dashboard/rear tray.
•Do not attach labels, or use discs with sticky ink/ residue. Such discs may stop spinning when used, causing a malfunction, or may ruin the disc.
•Do not use any discs with labels or stickers attached.
The following malfunctions may result from using such discs:
–Inability to eject a disc (due to a label or sticker peeling off and jamming the eject mechanism).
–Inability to read audio data correctly (e.g., playback skipping, or no playback) due to heat shrinking of a sticker or label causing a disc to warp.
•Discs with non-standard shapes (e.g., heart, square, star) cannot be played on this unit. Attempting to do so may damage the unit. Do not use such discs.
•You cannot play 8 cm (3 1/4 in) CDs.
•Before playing, clean the discs with a commercially available
cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analog discs.
Notes on CD-R/CD-RW discs
•Some CD-Rs/CD-RWs (depending on the equipment used for its recording or the condition of the disc) may not play on this unit.
•You cannot play a CD-R/a CD-RW that is not finalized.
CDX-GT285S/GT280S only
•The unit is compatible with the ISO 9660 level 1/ level 2 format, Joliet/Romeo in the expansion format, and Multi Session.
•The maximum number of:
–folders (albums): 150 (including root and empty folders).
–files (tracks) and folders contained in a disc: 300 (if a folder/file names contain many characters, this number may become less than 300).
–displayable characters for a folder/file name is 32 (Joliet), or 64 (Romeo).
•When the disc is recorded in Multi Session, only the first track of the first session format is recognized and played (any other format is skipped). The priority of the format is CD-DA and MP3/WMA.
–When the first track is a CD-DA, only CD-DA of the first session is played.
–When the first track is not a CD-DA, the MP3/ WMA session is played. If the disc has no data in any of these formats, “NO MUSIC” is displayed.
Music discs encoded with copyright protection technologies
This product is designed to play back discs that conform to the Compact Disc (CD) standard. Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that do not conform to the CD standard and may not be playable by this product.
Note on DualDiscs
A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. However, since the audio material side does not conform to the Compact Disc (CD) standard, playback on this product is not guaranteed.
