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 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
— the tape does not record.
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.
