Before placing a cassette in the
tape deck

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 etc.
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
When the tape heads become dirty;
— the sound is distorted
— there is a decrease in sound level
— the sound drops out
— the tape does not erase completely

Make sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
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 every 20 to 30 hours of use
with a separately sold demagnetizing cassette. For
details, refer to the instructions of the demagnetizing
cassette.
