HANDLING DISCS
●Using discs
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.
• When recording images,
the DVD video camera/
recorder may avoid the
portions of disc where
recording is not possible,
due to dust, scratches,
etc. [It will pause m at
such a portion and
automatically restart
recording (n).]
This will cause recording to be interrupted for
several seconds to several minutes, and
multiple thumbnails will be created by one
recording session as shown above. In this case,
the recordable time on disc will decrease.
• Be careful when removing the disc since the
metal of removal slot of DVD video camera/
recorder, and disc itself, may be hot.
●Storing discs
• When storing disc, replace it in the plastic case
in which it was purchased.
• Be careful that no condensation occurs on disc.
• Do not place disc in following places:
− Direct sunlight for a long time
− Where humidity is high or in dusty place
− Where there is heat from a heater, etc.
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).
