Care and Handling of Discs

How to handle discs
When handling a disc, do
not touch the surface of the
disc. Since discs are made
of plastic, they are easily
damaged. If a disc gets dirty,
dusty, scratched or warped,
the images and sound will
not be picked up correctly,
and such a disc may cause the unit to malfunction.

Label side
Do not damage the label side, stick paper to or use any adhesive
on its surface.

Storage

Make sure that discs are kept in their cases. if discs are piled on
top of one another without their protective cases, they can be
damaged. Do not put discs in a location where they may be
exposed to direct sunlight, or in a place where the humidity or
temperature is high. Avoid leaving discs in your car!

Maintenance of discs

If there are fingerprints or other dirt
adhering to a disc, wipe with a soft dry
cloth, moving from the center outwards.
If a disc is difficult to clean, wipe with a
cloth moistened with water. Never use
record cleaners, petrol, alcohol or any
anti-static agents.
