Troubleshooting
To be continued....
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 antenna 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 be neither played back nor
ejected.
• Unlock the disc (see page 15).
• Eject the disc forcibly (see page 2).
• Disc sound is sometimes interrupted. • Stop playback while driving on rough roads.
• Use an unscratched disc.
• Check the cords and connections.
• “NO DISC” appears on the display. Insert a correct 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 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.
• “NO FILES” appears on the display. Insert a disc that contains MP3/WMA tracks.
Tape playback
• A cassette cannot be inserted. Insert the cassette with the exposed tape facing
right.
• Cassette can be neither played back nor
ejected.
Unlock the cassette (see page 17).
• “NO TAPE” appears on the display. Insert a cassette correctly.
• Cassette tapes become hot. This is not a malfunction.
• Tape sound is at very low level and
sound quality is degraded.
Clean the tape head using a head cleaning tape.
