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

two-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.

Playing tracks in random
order — Shuffle Play

You can select:

•SHUF-1 – to play the tracks on the current

disc in random order.

•SHUF-2 – to play the tracks in the current

unit in random order.

•SHUF-ALL – to play all the tracks in all the

units in random order.

1 During playback, press (SHIFT), then

press (3) (PLAY MODE) repeatedly until

2 Press (4) (n) repeatedly until the

desired setting appears.

z SHUF-1 z SHUF-2

SHUF-OFF Z SHUF-ALL Z

Shuffle Play starts.

3 Press (SHIFT).

To return to normal playback mode, select
“SHUF-OFF” in step 2 above.

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.

15

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 a 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.

Maintenance

Fuse Replacement

When replacing the fuse, be sure to use one
matching the amperage rating stated on the
original 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)

Warning

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

• The sound may become distorted while
playing the cassette. The cassette player head
should be cleaned after each 50 hours of use.

Cassettes longer than 90 minutes

The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tape used for these cassettes is very
thin and tends to stretch easily. Frequent
playing and stopping of these tapes may cause
them to become entangled in the cassette deck
mechanism.

16

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.
