• Use a head demagnetizer (available at electronics and
audio shops) to demagnetize the heads (when the System is
turned off).
Cleaning the System

is heavily stained, wipe it with a cloth soaked in water-
diluted neutral detergent and wrung well, then wipe clean
with a dry cloth.

damaged or get its paint peeled off, be careful about the
following:
– DO NOT wipe it with a hard cloth.
– DO NOT wipe it forcefully.
– DO NOT wipe it with thinner or benzine.
– DO NOT apply any volatile substance such as
insecticides to it.
– DO NOT allow any rubber or plastic to remain in contact
for a long time.
