Maintenance
Warning:
• Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body
and lens. Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.
Caution:
• Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance
on the projector.
• Ask your dealer for annual cleaning of the inside of the projector. If you continue to use the projector with dust
inside, it may result in fire or malfunction.
Cleaning of the projector and the vents
Use a soft cloth to clean the projector and the vents. When the vents become dirty, wipe them with a soft cloth
dampened with diluted mild detergent, and then wipe them with a dry cloth.
To protect the surface of the projector from fading or deteriorating:
• Do not spray insecticide on or inside the projector.
• Do not use benzin or thinner to clean it.
• Do not let rubber or plastic materials contact with projector.
Cleaning of the lens
Remove dust or dirt using the commercially available lens care products (such as cleaning paper or cloth for lens
and blower brush).
• Since the lens surface is sensitive, do not scrub it with a solid object or tap on it.
• Do not wipe the lens with lens cleaner or solvent containing alcohol. Doing so may cause wipe marks or peel off
the lens coating and the focus performance may be affected.
• Make sure to clean the lens after the lamp is turned off and the lens is cooled sufficiently.
