Malfunctions with individual CDs/DVDs

If malfunctions only occur with individual CDs/
DVDs, one of the following factors may be the
cause.

Self-recorded CDs/DVDs

Possible reasons for malfunctions with self-
recorded CDs/DVDs are, e.g. inconsistent data-
creation or recording processes, or poor quality
or high age of the CD/DVD blank.
Only label CDs/DVDs on the top, with a pen
designed for this purpose.

Damaged CDs/DVDs

Avoid leaving fingerprints, as well as dust,
scratches or moisture on the CDs/DVDs.
Keep CDs/DVDs in protective sleeves or cases.
Do not subject CDs/DVDs to temperatures over
122

7/506, high levels of humidity or direct

sunlight.

CDs/DVDs with copy protection

CDs/DVDs are often copy-protected by the
manufacturer. This can mean that some CDs/
DVDs cannot be played or can only be played to
a limited extent.

Care

Clean the reflective signal side of CDs/DVDs as
needed by wiping it with a commercially avail-
able cleaning tissue in straight lines from the
center of the disc outwards.
