Sony CCD-TRV512 User Manual

To ensure normal recording and clear pictures, clean the video heads. When v
appears in CAMERA mode or playback pictures are “noisy” or hardly visible, the
video heads may be dirty.

[a ]  Slightly dirty
[b]  Dirty
If this happens, clean the video heads with the Sony V8-25CLH cleaning cassette (not
supplied). After checking the picture, if it is still “noisy”, repeat the cleaning. (Do not
repeat cleaning more than 5 times in one session.)

Caution
Do not use a commercially available wet-type cleaning cassette. It may damage the
video heads.

Note
If the V8-25CLH cleaning cassette is not available in your area, consult your nearest
Sony dealer.
