Notes on Video Head Cleaning
To ensure clear picture, clean the video heads
periodically |W-3|
When playback pictures are noisy or hardly
visible, the video heads may be contaminated.
[a] shows slight contamination.
[bj shows critical contamination.
In such cases:
1 Clean the video heads with the optional Sony
V8-25CLH cleaning cassette referring to the
instructions supplied with it.
2 After cleaning, check if the picture is clear by
recording or playing back with an ordinary
tape.
3 If the picture is still noisy, repeat cleaning. (Do
not repeat cleaning more than 5 times.)
If the V8-25CLH cleaning cassette is not available
in your area, consult your Sony service facility.
Caution
Do not use a commercially available wet-type
cleaning cassette. It may damage the video heads.
