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 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.)
When cleaning with a cotton swab, wipe the recording/playback
head, erasure head (deck 2 only), capstans, and pinchrollers.

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
● 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.
