HEAD CLEANING

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
The 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 recommendations for normal maintenance based upon your location, use patterns
and machine age.
