MAINTENANCE

Warning:
Never use flammable air duster or other materials when
cleaning the air-filter. Flammable substances may ignite
causing fire or backdown when the lamp is illuminated.
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.
Cleaning of the air-filter
Clean the air-filter frequently (about once a month). If the
filter or ventilation grilles become clogged with dirt or
dust, the temperature inside the projector may rise and
cause troubles, such as damage to the inside parts and
shortening the life of the panels.
When the temperature inside the projector rises, the
STATUS indicator will blink orange and the lamp will be
turned off.
1. Remove the air-filter.
2. Wash the air-filter or change it with a new filter.
Use water or diluted mild detergent to clean the filter.
Rinse the fi lter thoroughly and let it dry completely in
a shaded area.
Do not clean the filter with a vacuum cleaner. The
filter is soft and may be damaged.
3. Attach the air-filter.
Check that the left and right claws are locked onto the
unit.
Important:
If the filter is damaged or becomes extremely dirty,
change it with a new filter. Contact your dealer for a new
filter.
Use the dedicated filter only.
Caution:
Be sure to use the projector with an air-filter. If not, dust
may get inside the projector causing fireand failure.
Cleaning of the projector and the ventilation
slots
Use a soft cloth to clean the projector and the ventilation
grilles. When the grilles 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 benzine or thinner to clean it.
Do not let rubber or plastic materials contact with
projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens tissue
dampened with lens cleaning fluid. The lens surface is
fragile. Use only recommended, nonabrasive lens-cleaning
materials. Do not touch the lens with your fingers.
