Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
!
Only use CDs, which bear the label
shown and that conform to the com-
pact disc digital audio standard
(IEC 60908).
Do not play single-CDs (80 mm) with an
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.
