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.
However, 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 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.

Slack

• Distorted cassettes and loose labels can cause
problems when inserting or ejecting tapes.
Remove or replace loose labels.

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.

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.

Maintenance

Dismounting the unit

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.

Fuse (10 A)

Release key (supplied)

Cleaning the Connectors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
open the front panel by pressing (RELEASE),
then detach it and clean the connectors with a
cotton swab dipped in alcohol. Do not apply
too much force. Otherwise, the connectors may
be damaged.

Additional Information

Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.

You can control this unit with the optional
rotary remote (RM-X2S).
Some labels are supplied with the rotary
remote. Attach that label which matches the
functions of the master unit and the mounting
position of the rotary remote.
When you mount the rotary remote, attach the
