General notes on CD mode
Should excessively high temperatures oc-
cur while the audio system is in CD mode, TEMP HIGH
will appear in the display and
muting will take place. The unit will then
switch back to radio mode until the tem-
perature has decreased to a safe operating
level.
Should excessively low temperatures oc-
cur while the audio system is in CD mode,
TEMP LOW
will be displayed, but the CD will
still be played. It will be sensitive to skip-
ping if you are driving over rough roads.
Handle CDs carefully to prevent interfer-
ence during playback.
Avoid fingerprints and dust on CDs. Do not
write on the CDs or apply any label to the
CDs.
Clean CDs from time to time with a com-
mercially available cleaning cloth. No sol-
vents, anti-static sprays, etc. should be
used. Replace the CD in its container after use.
Protect CDs from heat and direct sunlight.
Only use CDs which bear the label shown
and that conform to the compact disc dig-
ital audio standard (IEC 60908). You can
therefore only use CDs with a maximum
thickness of 1.3 mm.
!Your CD drive has been designed to
play CDs which correspond to the EN
60908 standard. 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
drive.
Use of CDs which do not meet this
standard may cause damage to the CD
changer. Do not play single-CDs
(80 mm) with an adapter.
Warning!
G
The CD changer* is a Class 1 laser product.
There is a danger of invisible laser radiation
if the cover is opened or damaged.
Do not remove the cover. The CD changer*
does not contain any parts which can be ser-
viced by the user. For safety reasons, have
any service work which may be necessary
performed only by qualified personnel.
