Malfunctions with individual CDs/DVDs
If malfunctions occur only with particular CDs/
DVDs, this can be due to one of the following
causes.
Home-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 advanced age of the CD/DVD blank.
Label CDs/DVDs only on the top, using a marker
designed for this purpose.
Damaged CDs/DVDs
Avoid fingerprints dust, scratches, and mois-
ture.
Keep CDs/DVDs in a sleeve.
Do not subject CDs/DVDs to temperatures over
122
7/506, high levels of humidity or direct
sunlight.
CDs/DVDs with copy protection
Manufacturers often provide CDs/DVDs with
copy protection. This can mean that some CDs/
DVDs cannot be played or can only be played to
a limited extent.
Care
If necessary, clean the reflective scanning side
of the CDs/DVDs with a commercially available
cleaning cloth by wiping in straight lines from
the center outward.
