LCD panel type check
There are 2 types combination of the LCD panel/prism assembly and the optical parts, named Type-R and Type-L.
Since both have no compatibility, each type should be combined with the same type, and the specific parts should
be used. If not, the poor optical characteristics may degrade the quality of a projected image.
Confirm the "R" label or "L" label on top of the LCD panel/ prism assembly and optical unit.

Care the Polarized glass (IN) assy to maintain with the follow-
ing points.
- When removing the dust on the outer surface of the Polarized
glass (IN) assy, wipe with the soft cloth gently.
- When removing the dust on the inner surface of the Polarized
glass (IN) assy, The inner surface (light incoming side) of
the Polarized glass(IN/B)1 and Polarized glass-(IN/G)1 have
a very sensitive surface. Never touch or wipe the surfaces.
When removing the dust, use a commercial (inert gas) air
spray to remove them. Never use organic solvents. Grab the
edge of the glass with new gloves when handling the polar-
ized glass.
