General Maintenance
Cleaning the camcorder Heads
Dirt can accumulate on the video heads on the camera causing the playback picture to become blurred or appear
as if video information is lost. This often means that the video heads are dirty. Use a video head cleaner such as
a dry type head cleaning tape to clean the heads.
If after cleaning the heads the picture does not clear up consult your nearest dealer or VCR service center for
professional head cleaning.
Cleaning the Lens and Picture Tube of the Electronic Viewfinder
The lens of the electronic viewfinder can be user-cleaned if dust, dirt, or other foreign matter adheres to it.
1. Rotate and remove eye cup.
2. Clean the picture tube face and lens.
To prevent scratching, use a soft non abrasive cloth, swab or lens cleaning paper.
3. Fit the projection of the eye cup into the groove in the viewfinder and rotate the eye cup in the direction of the
arrow.
Periodic Maintenance
A precision electromechanical device, the Hitachi VM-E520/E521A 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.
