Handling Precautions
Disc Handling Care
Do not use deformed, warped, or irregularly shaped discs.
Reading of disc may not be possible depending on the disc conditions (cracks, dirt, modi-
fication, data recording quality, copy protection, recording equipment/software that was
used to create the disc, etc.)
Before using a disc, carefully read the operating/handling instructions and package of the
disc.
If the discs are not handled appropriately, they may become dirty or scratched. Further-
more the writing speed may get slower and the data may not be correctly written on or
read from the disc. Other damage may cause a drive failure.
Note the following precautions.
E
• Do not touch the disc surface (the side with no printing).
• Keep the disc surface clean and free from dirt, dust, fingerprints and scratches.
• Do not write on the surface of the disc with a ballpoint pen or other writing instrument.
• Do not attach stickers to discs.
• Do not drop, bend, or place heavy objects on top of discs.
• Do not place or store discs in locations exposed to heat, direct sunlight, humidity or dust.
• If a disc is brought from a cold to a warm location, condensation may form on the disc.
For read-only discs, wipe off the condensation using a soft, dry, lint-free cloth before
using the disc. For recordable/rewritable discs, wait until the condensation dries.
• When not using discs, keep them in their protective cases or cartridges.
To clean discs
<For read-only discs>
Wipe discs with a dry, soft cloth from
the center toward the edge.
If discs get very dirty, wipe with a moist,
soft cloth from the center toward the edge, then wipe again with a dry cloth to take up
remaining moisture.
<For recordable/rewritable discs>
Use the Panasonic disc cleaner to clean these discs.
Do not use a cloth, CD cleaners or any other such cleaners under any circumstances.
