About a tape longer than 90 minutes
The use of the tape with more than 90 minutes
of play time is not recommended except for
long, continuous recording or playback.
Cleaning the tape heads
Use a dry- or wet-type cleaning cassette
(available separately) after every 10 hours of
use, before you start an important recording, or
after playing an old tape. Failure to clean the
tape heads can cause degraded sound quality or
an inability of the unit to record or play tapes.
For details, refer to the instructions of the
cleaning cassette.
Demagnetizing the tape heads
Use a demagnetizing cassette (available
separately) after every 20 to 30 hours of use.
Failure to demagnetize the tape heads can cause
an increase in noise and a loss of high frequency
sound and an inability to completely erase tapes.
For details, refer to the instructions of the
demagnetizing cassette.
