Cleaning
Cleaning with air spray
1. Remove the cabinet top following to “Mechanical
Disassemblies”.
2. 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 opti-
cal 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”.
2. 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 cir-
cuit, never use any liquids (water, etc.) to clean the unit.
Use of liquid may cause the unit to malfunction.
