▷ Do not use self-recorded CDs/DVDs
with labels applied, as these can be‐
come detached during playback due
to heat buildup and can cause irrepar‐
able damage to the device.
▷ Only use round CDs/DVDs with a standard
diameter of 4.7 in/12 cm and do not play
CDs/DVDs with an adapter, e.g., single CDs;
otherwise, the CDs or the adapter may jam
and no longer eject.
▷ Do not use combined CDs/DVDs, e.g., DVD
Plus, as the CDs/DVDs can jam and will no
longer eject.◀
General malfunctions
▷ CD/DVD changers and players have been
optimized for performance in vehicles. In
some instances they may be more sensitive
to faulty CDs/DVDs than stationary devices
would be.
▷ If a CD/DVD cannot be played, first check
whether it has been inserted correctly.
Humidity
High levels of humidity can lead to condensation
on the CD/DVD or the laser's scan lens, and
temporarily prevent playback.
Malfunctions involving individual CDs/
DVDs
If malfunctions occur only with particular CDs/
DVDs, this can be due to one of the following
causes:
Home-recorded CDs/DVDs
▷ Possible reasons for malfunctions with
home-recorded CDs/DVDs are inconsistent
data creation or recording processes, or
poor quality or old age of the blank CD/DVD.
▷ Only label CDs/DVDs on the upper side with
a pen intended for this purpose.
Damage
▷ Avoid fingerprints, dust, scratches and
moisture.
▷ Store CDs/DVDs in a sleeve.
▷ Do not subject CDs/DVDs to temperatures
over 122 ℉/50 ℃, high humidity or direct
sunlight.
CDs/DVDs with copy protection
CDs/DVDs are often provided with a copy pro‐
tection feature by the manufacturer. This can
mean that some CDs/DVDs cannot be played or
can only be played to a limited extent.
