Do not attach labels of any type to the

pact disc digital audio standard

adapter. Only use round, 12 cm diame-
ter CDs.

Your CD changer has been designed to
play CDs which correspond to the IEC
60908 standard. Therefore only CDs
not exceeding a thickness of 1.3 mm
can be used.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected
and will damage the CD changer.

The CD changer may not be able to play
audio CDs with copy protection.
