Periodic Maintenance
A precision electromechanical device, the Hitachi VM-H57A requires maintenance after
a period of normal use. We expect that no other maintenance other than head cleaning
will be required during the period of warranty unless the camera/recorder is used either
heavily or seldom. Defective parts are covered by the warranty. Normal maintenance is
the responsibility of the owner. Consult your dealer or local VCR service center for
recommendations regarding normal maintenance based on your use patterns, location,
and the age of the camera/recorder.
