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

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

any source of magnetism. This will downgrade the sound quality
and cause noise.
