Maintenance
Cleaning the lens
If the lens becomes dirty, it may cause a
skipping of sound during CD operation.
Clean with a commercially available
blower.
Cleaning the tape heads and tape
path
Wipe the heads, the pinch rollers and
the capstans 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.

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.
Cleaning the cabinet
Clean the cabinet, panel and controls
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 alcohol or
benzine.
