Caring for Optical Discs

Handling of Discs:
Please hold the disc by gripping the rim or by placing the index finger in the
central hole. Never touch the signal surface, which is shiny. This applies to
both sides of double sided discs.
Cleaning of Discs:
Finger prints or stains on the surface of the disc may cause signal loss.
Depending on the degree of the stain, the reflected luminosity from the signal
surface may be weakened, resulting in degraded picture quality. Therefore,
please use a soft cloth and wipe in a radiating manner from the center of the
disc to the outer rims when cleaning the disc surface.
If the surface of your disc is very dirty, please wipe the disc with a moist cloth,
followed by a dry soft cloth to remove all water stains.
Never use electrostatic prevention products or solutions which contain
benzene, thinner or any other vaporizing substances, as they may damage
the disc surface.
Never add labels or adhesive tapes on the discs and be careful not to
scratch or damage the disc surface.
Storage of Discs:
To prevent discs from becoming bent or deformed, they should be vertically
kept in the disc storage case. To prevent damage, avoid leaving discs in your
car, where they may be subject to direct sunlight and high temperature.
Please thoroughly read the "Instruction Points for Attention" on the discs.
Cleaning the DVD Player:
The control panel and the case of the player will only require occasional wiping with a soft cloth. Areas with
stubborn stains can be cleaned with a soft cloth dipped in a neutral detergent. To prevent damaging the player,
never use vaporizing solutions.
Disc Accessories:
Do not use any disc accessory to improve the audio quality, disc protective solutions or lens cleaner. These
products may cause problems.
