Troubleshooting

What appears to be trouble is not always serious. Check the following points before calling a service center.

Symptom

Remedy/Cause

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.

Discs in general

•  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 11).
•  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.

•  “PLEASE” and “EJECT” appear alternately on 

the display.

This occurs sometimes due to over-heating. Eject the disc 
or change to another playback source.

MP3/WMA/AAC

•  Disc cannot be played back.

•  Use a disc with MP3/WMA/AAC tracks recorded in 

the format compliant with ISO 9660 Level 1, Level 2, 
Romeo, or Joliet.

•  Add the extension code <.mp3>, <.wma>, or 

<.m4a> to the file names.

•  Noise is generated.

Skip to another track or change the disc. (Do not add 
the extension code <.mp3>, <.wma>, or <.m4a> to 
non-MP3/WMA/AAC tracks.)

•  A longer readout time is required (“CHECK” 

keeps flashing on the display).

Do not use too many hierarchies and folders.
