CARE AND MAINTENANCE

To clean the cabinet

Use a soft and dry cloth.

If the surfaces are extremely dirty, use a soft cloth lightly moistened with mild detergent solution. Do not use strong solvents, such as alcohol, benzine or thinner as these could damage the finish of the unit.

To clean the heads and tape paths

After every 10 hours of use, clean the heads and tape paths with a head cleaning cassette or cotton swab moistened with cleaning fluid or denatured alcohol. (These cleaning kits are commercially available.)

After cleaning the heads and tape paths with a liquid head cleaning, cassette or a moistened swab, wait until the cleaned parts are completely dry before inserting the tapes.

To demagnetize the heads

The heads may become magnetized after long-term use. This may narrow the output range of recorded tapes and increase noise. After 20 to 30 hours use,’ demagnetize the heads with any commercially available demagnetizer.

Care of discs

QWhen a disc becomes dirty, wipe the disc from the center out with a cleaning cloth.

●After playing a disc, store the disc in its case. Do not leave the disc in places that are hot or humid.

Care of tapes

●Store tapes in their cases after use.

●Do not leave tapes near magnets, motors, television sets, or any source of magnetism. This will downgrade the sound quality and cause noise.

●Do not expose tapes to direct sunlight, or leave them in a car parked in direct sunlight.
