your discs, tapes and the mechanism clean.

cabinets or on shelves.
Cleaning the unit

Should be wiped off with a soft cloth. If the unit is heavily
stained, wipe it with a cloth soaked in water-diluted neutral

damaged or have its paint peel off, be careful about the
following:

– DO NOT wipe it with thinner or benzine.
– DO NOT apply any volatile substance such as an
insecticide to it.

with it for a long time.
Handling discs

holding it at the edge while pressing
the center hole lightly.
• Do not touch the shiny surface of the
disc, or bend the disc.
• Put the disc back in its case after use
to prevent warping.
• Be careful not to scratch the surface
of the disc when placing it back in
its case.
• Avoid exposure to direct sunlight,
temperature extremes, and moisture.
To clean the disc
Wipe the disc with a soft cloth in a
straight line from center to edge.

the disc.
