How to reset the operation time meter
Plug in the power cord, switch on the projector and re-
set lamp time by pressing the $, % and POWER but-
tons simultaneously.
Caution:
•The lamp you have removed, do not spill liquids on
it, place it near flammable objects or where children
can touch it. Otherwise, it will cause injury or fire.
•Be sure that the projector guide is firmly inserted
between the right and left lamp guides.
Important:
•The projector will not turn on if you do not secure
the lamp lid.
•The operation time meter must be reset after the
lamp has been replaced.
•Do not reset the operation time meter unless the
lamp has been replaced.
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
is in need of replacement. When lamp operation time
exceeds 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 up in red. The projector cannot be used
until the lamp has been replaced and operation timer
has been reset.
Caution:
•The light source 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 when
the lamp is used up in about 2,000 hours
and the projector wont come on until the
lamp is exchanged and operation timer
reset.

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
Clean the air-filter frequently. If the filter or ventila-
tion slots become clogged with dirt or dust, the tem-
perature inside of the projector may rise and shut off
the power (the TEMP indicator starts to blink red).
1. Press and raise the air-filter cover with a screwdriver
(–).
2. 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. If the filter is damaged or becomes
extremely dirty, contact your dealer for replacement
information.
3. Attach the air filter to the cover.
4. Reinstall the air-filter cover.
Note: 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
Use a soft cloth to clean the projector and the ventila-
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.
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 come into
contact with the projector.
Cleaning  the lens
Use a standard lens-cleaning brush or a piece of lens
tissue dampened with lens cleaning fluid. The lens sur-
face is fragile. Use only recommended, nonabrasive lens-
cleaning materials. Do not touch the lens with your fin-
gers.
