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 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.
Pinch roller
Capstan
Record/playback head
After cleaning, insert a tape when the areas
cleaned are completely dry.

Erase head
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.
