 Turning the power off1
Press the ON/STANDBY button.A message appears on the screen, confirming that you wish to shut off the power. This
message will disappear after a moment. (This operation is no longer valid after the
message disappears.)
2
Press the ON/STANDBY button again.The screen turns off, but the internal cooling fan continues to operate for a short while.
Then, the projector goes into standby mode.

A
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.
B
After the LAMP indicator goes off, the cooling fan continues to operate for a
short while in order to expel excess internal heat. If you are in a hurry, there is
no problem with unplugging the power cord in this state.
C
In standby mode.
Note
• The projector consumes about 6W of power in standby. We recommend you to unplug the
power cord if you will not use the projector for an extended period.
PRECAUTIONS
• Before unplugging the power cord, make sure that the LAMP indicator is off. Unplugging
the 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 power cord if the
projector locks up or acts abnormally.
• If the 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.39
, and replace it periodically. Contact the store where you
purchased your projector, or your local Service Station for replacement air filters.

 Connecting the power cord1
Insert the power cord connector into the AC IN socket of the projector.
2
Insert the 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: ON, 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.33
.
• The first time you use the projector after purchase, after the start-up screen disappears, the
Language menu is displayed p.24
.
When the power cord is plugged in, the following
three green indicators will come on for several
seconds: ON, TEMP, and LAMP. Next, the ON
indicator will change to orange, indicating standby
mode.
(Do not perform any operations while the 3 green
indicators are on.)

Adjusting the volume with the 
 
 buttons
The speaker volume can be adjusted when an audio signal is being input.Notes
•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.46
, 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.

Maintenance

Locking the white balance
Although the projector’s camera is constantly adjusting the color balance of the images
it photographs, the color balance may be disrupted, depending on the color layout of
the document, etc. If this happens, the white balance can be locked using the proce-
dures below.
1
Lay down a piece of white paper, and adjust so it fills the screen.Adjust the camera head and arm so that the white paper fills
the screen completely.
2
Set the White balance to Lock in the
Default menu. 
p.32
The white balance is locked. If you want to return to the auto adjustment, set the White
balance to Auto in the Default menu.Notes
•White balance setting to Fixed, if power is turned off, will be back to Auto.
•The color of the room lighting may prevent the white balance from being adjusted to the
optimum level. In this situation, or if you want to use a certain tinting, adjust the R-level,
G-level and B-level on the Image adjustment menu 
p.32
.
Using the document camera (Continued)
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 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
