Cleaning the cabinet
Clean this system with a soft cloth slightly
moistened with a mild detergent solution. Do
not use any type of abrasive pad, scouring
powder, or solvent, such as thinner, benzine, or
alcohol.
To prevent a tape from being
accidentally recorded over
Break off the cassette’s overwrite protection
tab from side A or B as illustrated.
Break off the
cassette tab
To later reuse the tape for recording, cover the
broken tab with adhesive tape.
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 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, a loss of
high frequency sound, and an inability to
completely erase tapes. For details, refer to the
instructions of the demagnetizing cassette.
