Cleaning and maintenance
Before carrying out cleaning and maintenance, be
sure to disconnect the power cord plug from the
wall outlet.
Wipe the cabinet with a soft, dry cloth.
If the cabinet is particularly dirty, soak the cloth in water with a small amount
of neutral detergent in it, squeeze the cloth very well, and then wipe the
cabinet. After cleaning, wipe the cabinet dry with a dry cloth. If using a
chemically-treated cloth, read the instructions supplied with the cloth before
use.
Do not wipe the lens with a cloth that is dusty or which produces lint.
If any dust or lint gets onto the lens, such dust or lint will be magnified and
projected onto the screen. Use a blower to clean any dust and lint from the
lens surface, or use a soft cloth to wipe off any dust or lint.
