How to use this manual This manual mainly explains operations using the remote, but the same operations can also be performed using the buttons on the unit having the same or similar names. Playable discs You can play back the following discs on this system. Other discs cannot be played back.
Notes on CD-R and CD-RW • Some CD-Rs or CD-RWs cannot be played on this system depending upon the recording quality or physical condition of the disc, or the characteristics of the recording device. Furthermore, the disc will not play if it has not been correctly finalized. For more information, see the operating instructions for the recording device. • Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the driver’s characteristics.
