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 unit 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.
To clean the tape heads
Dirty tape heads cause sound deterioration. After every 10
hours of use, clean the tape heads with a head cleaning
cassette. Refer to the instructions of the cleaning cassette.
To demagnetize the tape heads
Use a demagnetizing cassette after every 20 to 30 hours of
use. Refer to the instructions of the demagnetizing cassette.
Care of CDs
When a CD becomes dirty, wipe it from the center out with a
cleaning cloth. After playing a CD, store it in its case. Do
not keep it in hot or humid places.
Care of tapes
Store tapes in their cases after use. Do not leave tapes near
magnets, motors, television sets, or any source of
magnetism. Do not expose tapes to direct sunlight, or leave
them in a car parked in direct sunlight.
