Maintenance

Handling discs
• When removing the disc from its case, hold 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.
• 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.
Handling USB mass storage class devices
• Do not touch the USB connector.
• Be careful not to damage the USB connector.
• Put the USB connector in the cover or slide in the USB unit
after use to prevent breaking.
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, it 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 strongly.
– 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.
