Handling Discs; Disc Cleaning - Hitachi DZ-MV730A Instruction Manual

HANDLING DISCS

●Using discs
DVD-RAM and DVD-R discs are very delicate
recording media. Carefully read the following
cautions and observe them:
• Always use a brand new disc when recording
important material.
• Be sure not to touch the recording surface of
disc, or dirty or scratch it.
• If there is dust, scratch, dirt on disc or if it is
warped, the following phenomena may occur:
− Block noise in playback
image
− Momentary stop of
playback image
− Sound interrupted during
playback, or abnormal
sound
− Blue thumbnail
display* (Fig. 1)
− Disc cannot correctly
be recognized
− Disc cannot be
initialized
− Delay between video
and audio
Even if disc is normal, the above phenomena
may occasionally occur. While the ACCESS/
PC indicator is lit, do not subject disc to
vibrations or impact, and avoid using DVD
video camera/recorder at extremely high or
low temperatures, or in environment where
condensation is likely to occur.

DISC CLEANING

Use the disc cleaning cloth provided to lightly
wipe off any dirt adhering to the disc as shown
in the figure. Do not wipe the disc with force:
Doing so could cause scratches.
Never use solvent (thinner, water, antistat or
detergent) for cleaning.
Lightly wash the dirty cleaning cloth with
detergent: The dirt removal capacity of the cloth
will improve (rinse the cloth well with water so
that no detergent remains).

etc. [It will pause m at
such a portion and
