If malfunctions occur only with particular CDs/ DVDs, this can be due to one of the following causes.

Copied or self-recorded CDs/DVDs

▷ Possible reasons for malfunctions with home-recorded CDs/DVDs are inconsistent data creation or recording processes, or poor quality or old age of the blank CD/DVD.
▷ Only label CDs/DVDs on the upper side with a pen intended for this purpose.

Damaged CDs/DVDs

▷ Avoid fingerprints, dust, scratches and moisture.
▷ Store CDs/DVDs in a sleeve.
▷ Do not subject CDs/DVDs to temperatures over 122 ℉/50 ℃, high humidity or direct sunlight.

CDs/DVDs with copy protection

CDs/DVDs are often provided with a copy protection feature by the manufacturer. As a result, some CDs/DVDs cannot be played, can only be played to a limited degree, or cause the system to switch off. In this case, wait a short while and then switch the system back on again. Then remove the CD/DVD from the drive.

CDs/DVDs with compressed audio files

If the language set for the CD/DVD player does not match the language of the music track, the music tracks may be displayed incorrectly.
