3Insert the new lamp unit fully
inside and fasten the screws.
Fasten the two screws with a flat-end screwdriver.
CAUTION
¥ Do not touch the glass surface of the light-source lamp
directly with your hand as well as staining it. If you touch
with a bare hand, stains on your hand may adhere to the
lamp, possibly preventing the lamp from performing as
specified due to a shortened lamp life, a darkened screen,
etc. To handle a new light-source lamp, hold its plastic
part. Never touch the  metal part or the front glass
surface.
CAUTIONS
¥ Install the lamp unit and close the lamp-replacement opening cover correctly; otherwise, a safety switch is activated
to prevent the projector from operating.
¥ If the claw on the lamp-replacement opening cover is damaged, the projector may not possibly operate. Then, replace
with a new lamp-replacement opening cover.
¥ After replacing the lamp, be sure to reset the lamp use time (see pag e 50).
4Replace the lamp-replacement

Replacing the Light-source Lamp (Cont.)
Resetting the Lamp Use Time
After replacing with a new light-source lamp, reset the counter inside the projector. This works to reset the life calculation of the
light-source lamp, allowing the used time of the new light-source lamp to be accumulated.
1Turn on the MAIN POWER switch
to go into stand-by mode.
¥ON [ y ]:The main power turns ON and the STAND BY
indicator lights.
2Press and hold down the ÒVIDEOÓ,
ÒSETTINGÓ and ÒQUICK ALIGN. +
3Ó at the same time for six
seconds or more.
¥ The STAND BY and OPERATE indicators come on at
the same time.
3While the STAND BY and
OPERATE indicators are on, press
the ÒVIDEOÓ,  ÒSETTINGÓ, and
ÒCOMPUTERÓ buttons at the same
time.
¥ The STAND BY and OPERATE indicators blink two
seconds alternately, and after blinking, the projector
returns to stand-by state (the STAND BY indicator lights).
* This completes the resetting of the lamp use time.
Memo
To check the lamp use time has been reset :
You can check it by LAMP TIME on the OPTIONS menu.
CAUTIONS
¥ After replacing with a new light-source lamp, be sure to
reset the lamp use time. When the lamp use time
indicates 1000 hours, and if it is not reset, the projector
does not operate. (The light-source lamp does not turn
on.)
¥ Reset the lamp use time only when you have replaced
with a new light-source lamp. Never reset it at a halfway
time. Otherwise, the replacement time may become
unclear, degrade performance markedly, or cause lamp
explosion.

Cleaning and Replacing the Filter
Clean the filter periodically. If the filter is heavily stained and does not get clean, or if it is damag ed, replace the filter
with a new filter (part No.: LC30208). Otherwise, dirt may get inside and appear on the screen, possibly preventing you
from enjoying the video image fully. If dirt gets inside or if you need information about the filter, consult a authorized
dealer where you have purchased the projector or Service center.
1Turn off the MAIN POWER switch.
After the projector goes into stand-by state with the STAND BY indicator on, turn off the main power switch and pull out the
power cord from the projector and the wall outlet.
2Remove the filter.
Loosen the screw with a flat-end screwdriver.
Screw
Filter
Be careful not to
damage the claws.
3Clean the filter.
Clean the filter with a neutral detergent, wash it in water, and then dry it in the shade.
4Reinstall the filter.
Fasten the screw with a flat-end screwdriver.
Notes
¥ Install the filter correctly. Otherwise, the projector does not operate.
(Goes into an emergency mode.)
¥ If the filterÕs claws are damaged, the projector may not operate. Then,
replace with a new filter.
CAUTIONS
¥ Put on rubber gloves when using neutral detergent.
¥ After you have washed the filter in water, make sure the filter is
completely dry before reinstalling it. Otherwise, electric shock
or malfunction could occur.
¥ Do not clean the filter using a vacuum cleaner. Since the filter
is soft, it may be sucked into the vacuum cleaner or damaged.
Notes
¥ The screws are fitted so that they do not come off the filter.
¥ If the filter is clogged with dirt, etc., the projector goes into an
emergency mode (the EMERGENCY indicator blinks).
So, clean the filter periodically. For the emergency mode, refer to
pages 9 and 25.

Maintenance
¥ Stains on the cabinet
Should be wiped off with a soft cloth. If the cabinet is heavily stained, wipe it with a cloth soaked in water-diluted neutral
detergent and wrung well, then wipe clean with a dry cloth.
¥ Since the cabinet may deteriorate in quality, become damaged or get its paint peeled off, be careful about the following:
Ð Do not wipe it with a hard cloth.
Ð Do not wipe it strong.
Ð Do not wipe it with thinner or benzene.
Ð Do not apply any volatile substance such as insecticides to it.
Ð Do not allow any rubber or vinyl article to remain in contact with it for a long time.
¥ Stains on the lens
Sould be cleaned off with commercially available blowers or lens cleaning paper (for cleaning glasses and cameras).
Do not use liquid cleaning agents. This could cause the surface coating to be removed.
Do not rub or hit the lens as its surface is prone to damage.
