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.
• 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.
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.

damaged or get its paint peeled off, be careful about the 
following:
– DO NOT wipe it with a hard cloth.
