6-3 Precautions for Use
6.2 Maintenance
Use a blower to remove dirt or dust adhering to the CCD glass cover. Wiping
the glass forcefully can damage the glass or create static electricity that can
damage the CCD.
Use a soft, dry cloth to clean dirt off the exterior. If it is extremely dirty, use a
small amount of a neutral detergent on a cloth to remove it, and then wipe with
a dry cloth. Do not use alcohol or benzene, as they may discolor the surface
and cause peeling.
