Precautions
•If your car was parked in direct sunlight,
allow the unit to cool off before operating it.
•Power aerials will extend automatically
while the unit is operating.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
Moisture condensation
On a rainy day or in a very damp area,
moisture condensation may occur inside the
lenses and display of the unit. Should this
occur, the unit will not operate properly. In
such a case, remove the disc and wait for about
an hour until the moisture has evaporated.
To maintain high sound quality
Be careful not to splash juice or other soft
drinks onto the unit or discs.
Notes on discs
•To keep the disc clean, do not touch the
surface. Handle the disc by its edge.
•Keep your discs in their cases or disc
magazines when not in use. Do not subject
the discs to heat/high temperature. Avoid
leaving them in parked cars or on
dashboards/rear trays.
•Do not attach labels, or use discs with sticky
ink/residue. Such discs may stop spinning
when used, causing a malfunction, or may
ruin the disc.
•Do not use any discs with labels or stickers
attached.
The following malfunctions may result from
using such discs:
—Inability to eject a disc (due to a label or
sticker peeling off and jamming the eject
mechanism).
—Inability to read audio data correctly (e.g.,
playback skipping, or no playback) due to
heat shrinking of a sticker or label causing
a disc to warp.
•Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit.
Do not use such discs.
•You cannot play 8 cm CDs.
•Before playing, clean the discs with a
commercially available cleaning cloth. Wipe
each disc from the centre out. Do not use
solvents such as benzine, thinner,
commercially available cleaners, or antistatic
spray intended for analog discs.
