Additional
Information
Precautions
•If your car was parked in direct sunlight
resulting in a considerable rise in
temperature inside the car, allow the unit to
cool off before operating it.
•If no power is being supplied to the unit,
check the connections first. If everything is in
order, check the fuse.
•If no sound comes from the speakers of a
2-speaker system, set the fader control to the
center position.
•When the tape is played back for a long
period, the cassette may become warm
because of the built-in power amplifier. This
is not a sign of malfunction.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
Notes on handling CDs
A dirty or defective disc may cause sound
dropouts while playing. To enjoy optimum
sound, handle the disc as follows.
Handle the disc by its edge. To keep the disc
clean, do not touch the surface.
Do not stick paper or tape on the labeled
surface.
Do not expose the discs to direct sunlight or
heat sources such as hot air-ducts, or leave
them in a car parked in direct sunlight where
there can be a considerable rise in the
temperature inside the car.

Notes on Cassettes
Cassette care
•Do not touch the tape surface of a cassette, as
any dirt or dust will contaminate the heads.
•Keep cassettes away from equipment with
built-in magnets such as speakers and
amplifiers, as erasure or distortion on the
recorded tape could occur.
•Do not expose cassettes to direct sunlight,
extremely cold temperatures or moisture.
•Slack in the tape may cause the tape to be
caught in the machine. Before you insert the
tape, use a pencil or similar object to turn the
reel and take up any slack.
•Distorted cassettes and loose labels can cause
problems when inserting or ejecting tapes.
Remove or replace loose labels.
Cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tapes used for these cassettes are
very thin and tend to be stretched easily.
Frequent playing and stopping of these tapes
may cause them to be pulled into the cassette
deck mechanism.
Slack
Before playing, clean the discs with an
optional cleaning cloth. Wipe each disc from
the center out.
Do not use solvents such as benzine, thinner,
commercially available cleaners or antistatic
spray intended for analog discs.
Notes on moisture condensation
On a rainy day or in a very damp area,
moisture may condense on the lenses inside
the CD player. Should this occur, the unit will
not operate properly. In this case, remove the
disc and wait for about an hour until the
moisture evaporates.
To maintain high quality sound
If you have drink holders near your audio
equipment, be careful not to splash juice or
other soft drinks onto the car audio. Sugary
residues on this unit or cassette tapes may
contaminate the playback heads, reduce the
sound quality, or prevent sound reproduction
altogether.
Cassette cleaning kits cannot remove sugar
from the tape heads.

EN
Maintenance
Fuse Replacement
When replacing the fuse, be sure to use one
matching the amperage rating stated on the
fuse. If the fuse blows, check the power
connection and replace the fuse. If the fuse
blows again after replacement, there may be an
internal malfunction. In such a case, consult
your nearest Sony dealer.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.
