Maintenance information and precautions
Cleaning the video heads
To ensure normal recording and clear pictures, clean tile 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 _ indicator and "_ CLEANING CASSETTE" message appear one after another
or the _ indicator flashes on the screen.
If the above problem [a], [b] or [e] occurs, clean the video heads for 10 seconds with the
Sony DVMd2CED cleaning cassette (optional). Check the picture and if the above
problem persists, repeat cleaning.
[a] [b] [c]
If the video heads get dirtier, the entire screen becomes blue [e].
Note on the videohead
The videohead suffers from wear after long use. If you cannot obtain a clear image even
after using a cleaning cassette, it might be because the videohead is worn. Please contact
your Sony dealer or local authorized Sony service facility to have the videohead _-
replaced.
Cleaning the LCD screen
If fingerprints or dust make the LCD screen dirty, we recommend using the LCD
Cleaning Kit (optional) to clean the LCD screen.
