■ Maintenance and Cleaning
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.
● Cleaning with air spray
1. Remove the cabinet top following to "Mechanical Disassemblies".
2. Clean up the LCD panel and polarized glass by using the air spray from the cabinet top opening.
Caution:
Use only the supplied air blower and nozzle to keep the projector from being out of oder or damaged. We could not guarantee
the malfunction or breakage caused by other tools.
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.
● Disassembly Cleaning
Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be sufficiently
cleaned by air spraying alone.
Be sure to readjust the optical system after performing 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/Prism ass'y 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 multiple 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.
