10-4. Cleaning the DMD
 The DMD surface is glass and can be cleaned. However, avoid scratches as these can
have a direct influence on the image.

In case of dust on the DMD surface use an air cleaner ( with a device to prevent static, if
possible) to clean off the surface.
 In case of fingerprints, etc., add a small amount of water to the designated glass cleaner
and wipe off in one direction. Then use the designated dry glass cleaner to wipe off in the
same direction.
Caution:
Do not use absolute alcohol or other substances that could leave streaks after drying.
10-5. Cleaning the Main Unit
 Clean with a soft fuzz-free cloth. In case of severe soiling, use a well-wrung cloth dipped
in a neutral agent to remove soiling and then finish with a dry cloth.
 Do not clean with thinner, benzene or similar agents as this could lead to deterioration or
peeling of paint.
 In case of dust in suction or exhaust holes or the interior, disassemble the main unit and
use air to remove the dust from the inside.
