Caution:
¥ The light source lamp is fragile. Be careful not to
cut yourself with the 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 1,300 hours
and not used until  lamp replacement.
11 .Tighten up the screw of
the lamp lid using a
screwdriver (+).
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.
¥ Lamp cannot be removed from the projector unless
setting the lamp exchanging metal.
¥ If you do not have the lamp exchanging metal, re-
move the metal from the new lamp and use it.  Do
not touch the lamp directly.  It may be broken and
may cause you to injure or burn or yourself.
Caution:
¥ For the lamp you have removed, do not spill liquid
on it, place it near flammable objects or where chil-
dren 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.
Do not touch the lamp directly, place a cloth over
the replacement lamp.
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
1,000 hours of consecutive use. Life span may differ
according to operating environment, and may be shorter
than 1000 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 1,000 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 1,250 hours, the message ÒLAMP!!.Ó will appear
on the screen. When the lamp has been used for about
1,300 hours, the projector will automatically 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.

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 of
the power (the thermal indicator starts to blink red).
1. Press and raise the air-filter cover with a screw-
driver (Ð).
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
fingers.

3) Control sequence
(1) The command from a personal computer to the projector will be sent in 400ms.
(2) The projector will send a return command 400ms after it has received an encode. if the command isnÕt
received correctly, the projector will not send the retirn command.
(3) The personal computer checks the command and confirms that 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 by the personal computer side.
