Before placing a cassette in the
tape deck
Take up any slack in the tape. Otherwise the tape may
get entangled in the tape deck’s playing mechanism
and become damaged.
When using a tape longer than
90 minutes
The tape is very elastic. Do not change the tape
operations such as play, stop, and fast-winding etc.
too frequently. The tape may get entangled in the tape
deck’s playing mechanism.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
When the tape heads become dirty
— the sound becomes distorted
— the sound level decreases
— the sound drops out
— the tape does not erase completely
— the tape does not record
Make sure to clean the tape heads before making an
important recording or after playing an old tape. Use
a commercially available dry-type or wet-type
cleaning cassette. For details, refer to the instructions
of the cleaning cassette.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that
have contact with the tape after every 20 to 30 hours
of use with a commercially available demagnetizing
cassette. For details, refer to the instructions of the
demagnetizing cassette.
Cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with mild detergent solution. Do
not use any type of abrasive pad, scouring powder or
solvent such as thinner, benzene or alcohol.
