Troubleshooting
What appears to be trouble is not always serious. Check the following points before calling a service center.
Symptoms Remedies/Causes
General
• Sound cannot be heard from the speakers. • Adjust the volume to the optimum level.
• Check the cords and connections.
• The unit does not work at all. Reset the unit (see page 2).
FM/AM
• SSM automatic presetting does not work. Store stations manually.
• Static noise while listening to the radio. Connect the aerial firmly.
Disc playback
• Disc cannot be played back. 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 neither be played back nor ejected. • Unlock the disc (see page 13).
• Eject the disc forcibly (see page 2).
• 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
• 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 are not played back in the order you
have intended.
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.
• “PLEASE” and “EJECT” appear alternately on
the display.
Insert a disc that contains MP3/WMA tracks.
• Correct characters are not displayed (e.g.
album name).
This unit can only display letters (upper case), numbers,
and a limited number of symbols.
