GENERAL

CARE AND MAINTENANCE

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 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.
Use separately sold dry-type or wet-type cleaning cassette.
Refer to the instructions of the cleaning cassette for details.
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
• 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
• 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.
