CD player and CD changer 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 selfrecorded 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 moisture. Keep CDs/DVDs in a sleeve. Do not subject CDs/DVDs to temperatures over 1227/50 6, 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. 170 Online Edition for Part no. 01 41 0 013 312 - © 02/07 BMW AG
