During cooling, the LAMP indicator flashes. In this state, the power cannot be
turned back on. In addition, unplugging the power cord in this state will shorten
the life of the lamp.

After the LAMP indicator goes off, the cooling fan continues to operate for a
short while in order to expel excess internal heat.
C
In standby mode.
Note
• The projector consumes about 6W of power in standby. We recommend you to unplug
the AC power cord if you will not use the projector for an extended period.
PRECAUTIONS
• Before unplugging the AC power cord, make sure that the LAMP indicator is off.
Unplugging the AC power cord and cutting off the power while the projector is running or
being cooled will shorten the life of the lamp. However, please unplug the AC power
cord if the projector locks up or acts abnormally.
• If the AC power cord was unplugged before cooling was complete, give the lamp
sufficient time to cool before plugging it back in. If the lamp overheats, it may fail to light,
and its lifetime will be shortened.
LCD Panels
LCD panels wear out. In order to prolong the lifetime of your LCD panel, take the
following precautions.
• In order to extend the lifetime of the LCD panel, always turn off the power when not in
use, and make sure that the lamp is off. Keeping the lamp off is also very effective at
saving electricity.
• If the air filter becomes dirty and clogged, the projector’s internal temperature will rise,
shortening the lifetime of the LCD panel and causing malfunctions. Clean the air filter
from time to time 
p.32
, and replace it periodically. Contact the store where you
purchased your projector, or your local Service Station for replacement air filters.

Connecting the AC power cord1
Insert the AC power cord connector into the AC IN socket of the projector.
2
Insert the AC power cord plug into a wall or other power outlet.
Removing the lens cover
Be sure to remove the lens cover when the power is
turned on. If it is left on, it could become deformed due
to heat.

 Turning the power on
Press the ON/STANDBY
button.The power turns on, and the following
3 green indicators light: POWER,
LAMP, and FAN. After a moment, the
start-up screen appears. WARNING• Do not look into the lens during operation. Doing so could damage your vision. CAUTION•Do not block the air intake or exhaust. Doing so could cause a fire due to internal overheating.• Do not place your hands, face, or other objects near the air exhaust. Doing so could
cause burns, deform/break the object.Notes
• The start-up screen will disappear after a moment. You can dismiss the start-up screen before this
by performing any operation. You can also configure the start-up screen not to appear via the
Display setting menu 
p.31
.
• The first time you use the projector after purchase, after the start-up screen disappears, the
Language menu is displayed p.22
.
When the power cord is plugged in, the following
three green indicators will come on for several
seconds: POWER, TEMP, and LAMP. Next, the
POWER indicator will change to orange, indicating
standby mode.
(Do not perform any operations while the 3 green
indicators are on.)

•Note that because of the lamp characteristics, the brightness of the lamp may fluctuate slightly
.
• A lamp is a consumable supply.
If used for extended periods, images will appear dark, and the lamp could burn out.  This
is characteristic of a lamp, and is not malfunction. (The lifetime of the lamp depends on
conditions of use.)
• The LCD panel is made using extremely advanced technology, but there may be black
spots (pixels that do not light) or bright spots (pixels that are constantly lit) on the panel.
Please note that these are not malfunctions.
•
Although this projector supports a wide range of RGB signals 
p.38
, any resolutions not
supported by the model (XGA or SVGA, depending on the model) will expand or shrink the
pictures, and will affect image quality slightly. To view high-quality images, it is
recommended that the computer’s external output should be set to the projector’s resolution.
• With some models of computer having LCD displays or the like, displaying images
simultaneously on the projector and the monitor’s display may cause the images to be
shown improperly. If this happens, turn off the computer’s LCD display. For information on
how to turn off the LCD display, see the owner’s manual of your computer.
• If a signal not supported by the projector is input, the 
 icon will appear.
• If a no signal is being input from the connected device, the 
 icon will appear.
• If an unavailable operation button is pressed, the 
 icon will appear.

The air filter prevents dust and debris from getting inside the projector. Never run the
projector with the filter removed. It is recommended that the air filter is cleaned regularly.
•The icon message 
 “Check the air filter for dirt.” is displayed every 100 hours. (If the
usage time exceeds 100 hours, this message is displayed for 30 seconds when the image is
displayed for the first time after power is turned on. This display will be dismissed with any
operation.)
• Check out the filter and any debris is found, use the following procedure for cleaning.
 WARNING
• Request cleaning and maintenance of a ceiling-mounted unit from your projector
dealership.1
Unplug AC power cord.
2
Remove the air filter.Pull out the air filter by taking the catch shown in the figure.
3
Clean the filter.Carefully remove the dust and dirt from the air filter with a
vacuum cleaner or the like.
4
Replace the air filter.Notes
• Allowing dirt and dust to build up in the air filter will worsen the air circulation inside the
projector, causing the internal temperature to rise, causing the projector to stop working
or malfunction.
• Insert the air filter all the way in. Leaving gaps will allow dust and dirt to get inside the
projector again.
• If you wash the air filer with water, make sure to dry it completely before replacing it.
• If the air filter is torn, consult with your dealer about replacing it with a new one.
Continuing to use a ripped filter will allow dust and dirt to get inside the projector.Air filter cleaningMaintenance

❈After approx. one minute of abnormal display, the projector returns to
the standby state waiting for internal cool down.Power went out during use⇒Internal overheating, or the outside temperature is too high.
•Place the projector so that the air intake and exhaust are not blocked.
•Unplug the AC power cord and wait for a short while, then turn the
power back on.
•Clean the air filter.

PRECAUTIONS
•Make sure to unplug the AC power cord if something goes wrong.
•If the AC power cord is unplugged before cooling is complete, give the lamp enough time
to cool before plugging it back in. If the lamp overheats, it may fail to light. Unplugging the
AC power cord repeatedly when the temperature is high will shorten the life of the lamp.
(Even if you are not concerned about lamp lifetime, the light may not come on if you do
not wait at least 3 minutes.)
