1CD slot
2Magazine compartment buttonsThe CD changer has a built-in magazine
which can hold up to six CDs.
The CD changer has six magazine compart-
ment buttons 2 for controlling the loading
procedure.
LEDs in the buttons indicate the status of
the corresponding magazine compart-
ment.
Button LED OFF:
Magazine compartment empty
Button LED flashes green:
CD changer requesting CD to be load-
ed
Button LED continuously red:

CD
The status of a magazine compartment can
also be seen when selecting a CD in the CD
Selection menu (
page 71).
The CD slot 1 for loading CDs into the CD
changer is located above the buttons 2.
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
Your CD drive 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 will become stuck and
damage the drive.
Data carriers which contain data on
both sides can cause play-back prob-
lems because the storage layers are
thinner than one-sided data carriers.
!
Do not play single CDs (80mm) with an
adapter. An adapter could become
stuck and damage the drive. Only use
12 cm diameter CDs.
i
The CD changer may not be able to play
audio CDs with copy protection.
