CARE AND MAINTENANCE

TROUBLESHOOTING GUIDE

Occasional care and maintenance of the unit and the software are needed to optimize the performance of your unit.

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 tape heads

When the tape heads are dirty;

-high frequency sound is not emitted

-the sound is not adequately high

-the sound is off-balance

-the tape cannot be erased

-the tape cannot be recorded on

After every 10 hours of use, clean the tape heads with a head cleaning cassette.

Refer to the instructions of the cleaning cassette for details.

To demagnetize the tape heads

The tape heads may become magnetized after long-term use. This may narrow the output range of recorded tapes and increase noise.

After every 20 to 30 hours of use, demagnetize the tape heads with a separately sold demagnetizing cassette.

Refer to the instructions of the demagnetizing cassette for details.

Care of discs

When 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
