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.

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.

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 ataryway 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

Maintenance

Fuse Replacement

When replacing the fuse, be sure to use one with the correct amperage which is stated on the fuse case. Never use a fuse whose amperage rating exceeds the one supplied to the unit as this could cause a malfunction of the unit.

Warning

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

Removing the unit

• 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.

To prevent the unit from being stolen

When you leave your car, remove the unit from the bracket and take it away with you.

Caution

Be careful when you remove the unit. The rear of the unit becomes very hot just after operating it because of a built-in power amplifer.
