• You must reset the operation time meter after
you replace the lamp.
• Do not reset the operation time meter unless the
lamp has been replaced.
Interval of the lamp replacement
The interval of the lamp replacement about 2,000 hours
of consecutive use. Replacement span may differ ac-
cording 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 safety 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 replacement span of the lamp depends on the
environment. For replacement lamps, please con-
tact your dealer.

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 (about once a month). If
the filter or ventilation slots become clogged with dirt
or dust, the temperature inside of the projector may
rise and cause some troubles, such as damage of in-
side parts, and shortening the life of panel.
•When the temperature inside of the projector
rises, the TEMP indicator blinks in red, and the
power will be shut off to be stand-by which LAMP
indicator is turned off.
For side air outlet grill
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.
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
grill
Use a soft cloth to clean the projector and the ventila-
tion grill. When the grill 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

							2 3) Control sequence
(1) Send the command from a personal computer to the projector. (The commands must be sent at least
400ms apart.)
(2) The projector will send a return command 400ms* after it has received an end code. If the command is
not received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the command which has been sent has been
executed or not.
(4) This projector sends various codes other than the return code. When having a control sequence by RS-
232C, reject other codes from personal computer side.
•* : The sending time of return command may delay depending on the condition (during changing the
input signal, etc.).
