mable objects or where children can touch it.  Oth-
erwise, it could cause injury or fire.
•Be sure that the projector guide is firmly inserted
between the right and left lamp guides.
The life of the lamp
The average life of the lamp for the projector is about
2,000 hours of consecutive use. Life span may differ
according to operating environment, and may be shorter
than 2,000 hours. Decreases in luminescence and/or
color brightness will indicate that the light source lamp
needs to be replaced. When lamp operation time ex-
ceeds 1,500 hours, the indicator will flash alternately
between green and red (while the lamp is in operation;
when the lamp is not in operation, the indicator will
appear red only).   When the lamp has been used for
about 1,900 hours, the message “LAMP!!.” will appear
on the screen for one minute. When the lamp has been
used for about 2,000 hours, the projector will automati-
cally shut off for the safety of the lamp and the power
indicator light will be red. The projector cannot be used
until the lamp has been replaced and operation timer
has been reset.
Caution:
•The lamp is fragile. If broken, be careful not to cut
yourself with glass fragments.
•The lamp life depends on the environment. For re-
placement lamps, please contact your dealer.
The projector automatically shuts off af-
ter about 2,000 hours, and you cannot use
the projector until you replace the lamp.

Maintenance
Caution:
Be sure to turn off the projector and unplug the power
cord from the wall outlet before you perform any main-
tenance on the projector.
Cleaning the air-filter
This projector has two air-filters, for bottom air-outlet
slots and for front air outlet slots. Clean the air-filter
frequently. If the filter or ventilation slots become clogged
with dirt or dust, the temperature inside the projector
may rise and shut off the power (the TEMP indicator
starts to blink red).
For bottom air outlet slots
1. To remove the filter cover, press the ridged
area gently, push the cover in the direction
of the arrow and lift.
2. Remove the air-filter from
the filter cover.
3. Wash the air-filter.
•Use water or a mild
detergent diluted with
water to clean the filter.
Rinse the filter thoroughly and let it dry
completely.
4. Attach the filter to the cover.
5. Reinstall the filter cover.
For front air outlet slots
1. To remove the filter cover, press the
two ridged area gently and pull the cover.
2. Remove the dust from the
air-filter by using a vacuum
cleaner.

filter.
3. Reinstall the filter cover.
Important:
•If the filter is damaged or becomes extremely
dirty, contact your dealer for replacement.
•The power will not turn on if the air-filter cover is
improperly installed.
Caution:
Be sure to use the projector with an air-filter. If not,
dust may get inside the projector, causing a fire or a
breakdown.
Cleaning the projector and the ventilation
slots

tion slots. When the slots become dirty, wipe them with
a soft cloth dampened with a diluted mild detergent,
and then wipe them with a dry cloth.
