Place the system in a location with adequate ventilation to prevent heat build up. Do not place the system in an inclined position. Do not place the system in locations where it is: Extremely hot or cold Dusty or dirty Very humid Subject to vibrations Subject to direct sunlight.

On heat build up

Although the system heats up during operation, this is not a malfunction. Place the system in a location with adequate ventilation to prevent heat build-up in the system. If you continuously use this system at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet. To prevent a malfunction, do not cover the ventilation hole for the cooling fan.

On operation

If the system is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lens inside the CD player. Should this occur, the system will not operate properly. Remove the CD and leave the system turned on for about an hour until the moisture evaporates. When you move the system, take out any discs. If you have any questions or problems concerning your stereo system, please consult your nearest Sony dealer.
Before placing a cassette in the tape deck
Take up any slack in the tape. Otherwise the tape may get entangled in the parts of the tape deck and become damaged.
When using a tape longer than 90 minutes
The tape is very elastic. Do not change the tape operations such as play, stop, and fast-winding frequently. The tape may get entangled in the tape deck.

Notes on CDs

Before playing, clean the CD with a cleaning cloth. Wipe the CD from the center out. Do not use solvents. Do not expose the CD to direct sunlight or heat sources.

Cleaning the tape heads

Clean the tape heads after every 10 hours of use. Be sure to clean the tape heads before you start an important recording or after playing an old tape. Use a separately sold dry-type or wet-type cleaning cassette. For details, refer to the instructions of the cleaning cassette.

Note on CD-R playback

Discs recorded on CD-R drives may not be played back because of scratches, dirt, recording condition or the drives characteristics. Besides, the discs, which are not yet finalized at the end of recording, cannot be played back.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that have contact with the tape every 20 to 30 hours of use with a separately sold demagnetizing cassette. For details, refer to the instructions of the demagnetizing cassette.
Optional Components/Additional Information

Cleaning the cabinet

Use a soft cloth slightly moistened with mild detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded over, break off the cassette tab from side A or B as illustrated. If you later want to reuse the tape for recording, cover the broken tab with adhesive tape.
