7 Handling Discs
• Remove the disc from its case by 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, extreme
temperature and moisture.
To clean the disc
Wipe the disc with a soft cloth in a straight line
from center to edge.
• DO NOT use any solvent — such as
conventional record cleaner, spray,
thinner or benzine — to clean the disc.
7 Cleaning the system
• Stains on the system should be wiped off with a soft cloth. If 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.
• Since the system may deteriorate in quality, become 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 with
it for a long time.
If there are any other cases than the noted above or if this system does not seem to work properly, turn off the system and turn it back on.
