Cleaning the tape heads and tape
path
Wipe the heads, the pinch roller and the
capstan with a cleaning swab slightly
moistened with cleaning fluid or alcohol
after every 10 hours of operation for
optimum playback and recording
quality. To make the best possible
recording, however, we recommend that
you clean all surfaces over which tape
travels before each recording.

areas cleaned are completely dry.
Demagnetizing the tape heads
After 20 to 30 hours of use, enough
residual magnetism will have built up
on the tape heads to begin to cause loss
of high frequency sound and hiss. At
this time, you should demagnetize the
heads and all metal parts in the tape
path with a commercially available tape
head demagnetizer.
