Handling precautions for DVD-ROM discs
• Handle DVD-ROM discs carefully. Any DVD-ROM disc with excessive
warping or scratches on its surface can cause reading errors.
• Store DVD-ROM discs away from direct sunlight, which can cause
warping and render them unusable.
• DVD-ROM discs rotate at high speeds inside the system's main unit.
Never use a cracked or badly warped disc; doing so could damage
the unit.
• To clean a DVD-ROM disc, lightly wipe it with a soft cloth in straight
lines from the center hole toward the outer edge.
• Never clean DVD-ROM discs with benzene, thinner, record spray,
antistatic spray, or chemical swabs.
• Do not touch the DVD-ROM disc's data surface (the surface without
a printed label). A dirty data surface can cause reading errors. Always
hold a DVD-ROM disc by the center hole and at one point on the
outer edge, or by two points on the outer edge.
• Do not write anything on DVD-ROM discs or affix anything, such as
stickers, to them.
