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

the recordable time on disc will decrease.

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).
