Periodic Maintenance
A precision electromechanical device, the Hitachi VM-H620/H720A 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 camcorder 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 camcorder.
