Troubleshooting

The disc is ejected without order (or it comes out spontaneously).
Is the disc set properly (horizontally) on the disc tray?
Set the disc properly, and close the disc tray.
Is the disc dusty or dirty?
Remove dust or dirt from the disc using an air spray or a dry soft cloth. To avoid
damaging discs, wipe the disc gently from the center to the edge of the disc.
Does the drive accept other discs (audio CD, CD-ROM, blank CD-R disc, etc.)?
If a specific disc is ejected, the disc itself may be damaged or deformed.
If all discs are ejected, contact the store of purchase or your nearest Yamaha dealer
(listed at the back of this manual).

(Troubleshooting, Item 3)
Is the disc compatible with the drive? (P. 5, 37)
Be sure that the disc is compatible with the CRW-F1 drive.
Is the disc dusty or dirty?
Remove dust or dirt from the disc using an air spray or a dry soft cloth. To avoid
damaging discs, wipe the disc gently from the center to the edge of the disc.
Can data be read from other discs (audio CD, CD-ROM, etc.)?
If no data can be read from a specific disc, data may be written in a format that the
drive cannot recognize, or the disc itself may be damaged or deformed. Note that no
data can be read from blank discs, and the CRW-F1 drive infrequently fail to read
data correctly from a disc even if the disc is compatible with the drive.
