About Head cleaning

7If the picture playback becomes blurred, it does not mean that the recorded program has been erased.

7Dirt accumulated on the video heads after long periods of use causes such troubles. In this case, head cleaning requiring highly technical care is necessary.

7For head cleaning, consult the nearest JVC dealer.
