Storing discs
• If the camcorder is not used for long periods of time, remove the disc from the
camcorder.
• 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.
If the above countermeasures are not taken, the following symptoms 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
− A recording of one scene may be divided into plural scenes, or a portion of a scene
may not be recorded
− Recording/Playback is not possible
z 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).
