Additional
Information
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.
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 switching on.
• 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.
Fuse (15 A)
If you have any questions or problems
concerning your unit that are not covered in
this manual, please 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.

Notes on Cassettes
Cassette care
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 with a cotton swab
dipped in alcohol. Do not apply too much
force. Otherwise, the connector may get
damaged.
• 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.
• When the tape is played back for a long
period, the cassette shell may become warm
because of the built-in power amplifier.
However, this is not a sign of a malfunction.
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.
