Cleaning the video heads
To ensure normal recording and clear pictures, clean the video heads. The video heads
may be dirty when:
•Mosaic-pattern noise appears on the playback picture.
•Playback pictures do not move.
•Playback pictures do not appear.
•The x indicator and “
CLEANING CASSETTE” message appear one after another,
or the x indicator flashes on the screen during recording.
If the above problem [a], [b] or [c] occurs, clean the video heads for 10 seconds with the
Sony DVM-12CLD cleaning cassette (optional). Check the picture and if the above
problem persists, repeat cleaning.
If the video heads get dirtier, the entire screen becomes blue [c].
Cleaning the LCD screen
If fingerprints or dust make the LCD screen dirty, we recommend using the Cleaning
cloth (supplied) to clean the LCD screen. When you use the LCD Cleaning Kit
(optional), do not apply the cleaning liquid directly to the LCD screen. Clean the LCD
screen with cleaning paper moistened with the liquid.
