Cautions on handling discs
• Do not write on the printed side with a ball-point pen or
pencil.
• Do not use record cleaning sprays or antistatic. Also, do
not use volatile chemicals, such as benzene or thinner.
• Do not apply labels or stickers to discs. (Do not use
discs fixed with exposed tape adhesive or leftover
peeled-off stickers.)
• Do not use scratch-proof protectors or covers.
• Do not use discs printed with label printers available on
the market.
• Do not load warped or cracked discs.

Disc Storage

Be careful not to harm the disc because the data on
these discs is highly vulnerable to the environment.
• Do not keep under direct sunlight.
• Keep in a cool ventilated area.
• Store vertically.
• Keep in a clean protection jacket.
• If you move your DVD recorder suddenly from a cold
place to a warm place, condensation may generate on
the operating parts and lens and cause abnormal disc
playback. If this occurs, remove the disc and wait for one
to two hours with the power on before attempting
playback.
