General notes
Should excessively high temperatures oc-
cur while in CD mode,
CD TEMP HIGH
will
appear on the display and the CD will be
muted. The unit will then switch back to
the last operating mode used until the tem-
perature has decreased to a safe operating
level.
Should excessively low temperatures oc-
cur while in CD mode,
CD TEMP LOW
will ap-
pear on the display, but the CD will
continue to play.
Handle CDs carefully to prevent interfer-
ence during playback. Avoid fingerprints
and dust on CDs. Do not write on CDs or
apply any labels or other material to them.Only use original CDs. Using copied CDs
may create problems during playback.
Clean CDs from time to time with a com-
mercially available cleaning cloth. Do not
use solvents, anti-static sprays, etc. for
cleaning. Replace the CD in its case after
use. Protect CDs from heat and direct sun-
light.
Only use CDs, which bear the label shown
and that conform to the compact disc
digital audio standard (IEC 60908). You
can therefore only use CDs with a maxi-
mum thickness of 1.3 mm.
iUse 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.
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.Warning!

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.
