PREPARATIONS
Symptoms Remedies/Causes
General
• Sound cannot be heard from the speakers. • Adjust the volume to the optimum level.
• Check the cords and connections.

• Disc ejects. Insert the disc correctly.
• CD-R/CD-RW cannot be played back.
• Tracks on the CD-R/CD-RW cannot be
skipped.
• Insert a finalized CD-R/CD-RW.
• Finalize the CD-R/CD-RW with the component which you used
for recording.
• Disc can be neither played back nor ejected. • Unlock the disc.
• Eject the disc forcibly.
• Disc sound is sometimes interrupted. • Stop playback while driving on rough roads.
• Change the disc.
• Check the cords and connections.
• “NO DISC” appears on the display. Insert a playable disc into the loading slot.
MP3/WMA playback (for KD-S23 only)
• Disc cannot be played back. • Use a disc with MP3/WMA tracks recorded in the format
compliant with ISO 9660 Level 1, Level 2, Romeo, or Joliet.
• Add the extension code <.mp3> or <.wma> to the file names.
• Noise is generated. Skip to another track or change the disc. (Do not add the extension
code <.mp3> or <.wma> to non-MP3 or WMA tracks.)
• A longer readout time is required (“CHECK”
keeps flashing on the display).
Do not use too many hierarchies and folders.
• Tracks do not play back in the order you
have intended them to play.
Playback order is determined when the files are recorded.
• Elapsed playing time is not correct. This sometimes occurs during play. This is caused by how the
tracks are recorded on the disc.
