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, benzine or alcohol.
To save a tape permanently
To prevent a tape from being accidentally recorded
over, break off the cassette tab from side A or B as
illustrated.
If you later want to reuse the tape for recording, cover
the broken tab with adhesive tape.
Before placing a cassette in the tape
deck
Take up any slack in the tape. Otherwise, the tape may
get entangled in the parts of the tape deck 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
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use. Be
sure to clean the tape heads before you start an
important recording or after playing an old tape. Use a
separately sold 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 separately sold demagnetizing cassette. For
details, refer to the instructions of the demagnetizing
cassette.
