HEAD CLEANING - 37 - 3. Align the (•) mark on the eye cup with the (-) mark on the viewfinder, and then rotate the eye cup in the direction of the arrow until a click is heard. HEAD CLEANING • Picture playback may become blurred or be interrupted. This does not mean that the recorded program has been erased. • Dirt accumulated on the head after long periods of use causes this problem. In this case, head cleaning requiring highly technical care is necessary. • Consult your nearest dealer or VCR service center before using a head cleaning tape. PERIODIC MAINTENANCE This video camcorder is a precision electromechanical device which will require periodic maintenance after a period of normal use. We expect that no maintenance other than head cleaning will be required during the warranty period by most users, unless the video camcorder is heavily used or seldom used. Normal maintenance is the responsibility of the user, although defective parts are covered during the warranty period. Consult your VCR service center to determine the recommendations for normal maintenance based on your location, use patterns and machine age.
