Safety Instructions
WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and oper-
ate the audio system only when road, weath-
er and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
WarningG
The CD drive is a Class 1 laser product.
There is a danger of invisible laser radiation
when you open or damage the cover.
Do not remove the cover. The CD drive does
not contain any parts serviceable by the us-
er. For safety reasons, have any necessary
service work performed by qualified person-
nel.
Tips on data storage media
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
Do not play single-CDs (80 mm) with an
adapter. Only use 12 cm diameter CDs.
!
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 cannot be ejected
and will damage the drive.
Data carriers which contain data on
both sides can cause playback prob-
lems because the storage layers are
thinner than one-sided data carriers.
