Humidity
High levels of humidity can lead to condensa-
tion on the CD/DVD or the laser's scan lens and
temporarily prevent playback.
Malfunctions with individual CDs/DVDs
If malfunctions occur only with particular CDs/
DVDs, this may be due to one of the following
reasons.
Self-recorded CDs/DVDs
Possible reasons for malfunctions with self-
recorded CDs/DVDs are, for example, inconsis-
tent data-creation or recording processes, or
poor quality or old age of the CD/DVD blank.
Only label CDs/DVDs on the top, with a pen
designed for this purpose.
Damage
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
above 1227/50 6, nor to high humidity levels
or direct sunlight.

a limited extent.
