Maintenance
To get the best performance of the System, keep your
discs and mechanism clean.
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.
Cleaning the System
• Stains 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 for a long time.
