Maintenance
Cleaning with air spray
1. Remove the cabinet top following to “Mechanical
Disassemblies”.
. Clean up the LCD panel and polarizing plate by
using the air spray from the cabinet top opening.
Caution:
Use a commercial (inert gas) air spray designed for
cleaning camera and computer equipment. Use a
resin-based nozzle only. Be vary careful not to damage
optical parts with the nozzle tip. Never use any kind of
cleanser on the unit. Also, never use abrasive materials
on the unit as this may cause irreparable damage.
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized
glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.
Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean
the optical unit.
disassembly Cleaning
Disassembly cleaning method should only be per-
formed when the unit is considerable dirty and cannot
be sufficiently cleaned by air spraying alone.
Be sure to readjust the optical system after per-
forming disassembly cleaning.
1. Remove the cabinet top and main units following to
“Mechanical Disassemblies”.
. Remove the optical base top following to “Optical
Unit Disassemblies”. If the LCD panel needs
cleaning, remove the LCD panel unit following to
“LCD panel replacement”.
3. Clean the optical parts with a soft cloth. Clean
extremely dirty areas using a cloth moistened with
alcohol.
Caution:
The surface of the optical components consists of mul-
tiple dielectric layers with varying degrees of refraction.
Never use organic solvents (thinner, etc.) or any kind
of cleanser on these components.
Since the LCD panel is equipped with an electronic
circuit, never use any liquids (water, etc.) to clean the
unit. Use of liquid may cause the unit to malfunction.
Attaching the Lens Cover
When moving the projector or while it is not in use, replace
the lens cover.

Thread the string through the hole on the lens cover
and then tie a knot in the string to secure it in place.
Thread the other end of the string through the hole on
the bottom of the projector. Then pass the lens cover
through the resulting loop of the string and pull it to
tighten the knot.
