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

− Delay between video	*	Fig. 1
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 mat 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).

Use the disc cleaning cloth to clean from inner to outer edges in axial direction.
