Precautions
Lamp characteristics may rarely cause the brightness to fluctuate slightly.
The LCD panel is manufactured using high precision technology. There may be black spots
(pixels that do not light) or bright spots (pixels that are constantly lit) on the panel. These
are intrinsic characteristics of the manufacturing technology and are not malfunctions.
Notes
A lamp is a consumable item. 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.
Although this projector supports a wide range of RGB signals
p.
100
, any resolutions not
supported by this projector (XGA for X3241N, WXGA for WX3231N) will be expanded
or shrunk, which will slightly affect image quality. To view high-quality images, set the
computer’s external output to XGA for X3241N, WXGA for WX3231N.
With some computer models having LCD or similar displays, displaying images
simultaneously on the projector and the monitor’s display may prevent the images from
displaying properly. If this happens, turn off the computer’s LCD display. For information
on how to turn off the LCD display, see the computer’s owner’s manual.
A “No signal” message will appear if no signal is being input from the connected
equipment or if signal input is stopped while projecting.
If a signal not supported by the projector is input, the “Unsupported signal” message
will appear.
If an unavailable operation button is pressed, the icon will appear with a beep sound
(if the beep sound is set to [On]).
Moving pictures played back on computers using DVD software may appear unnatural
when projected with this projector. However, it is not a malfunction of the projector.

LCD Panels
LCD panels wear out. In order to prolong the lifetime of your LCD panel, take the
following precautions:
• To extend the lifetime of the LCD panel, always turn off the power when it is not in use,
and make sure that the lamp is off. Keeping the lamp off will also save 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. We recommend
regular and thorough cleaning of the air filter
p.94
.
• If the air filter becomes damaged, replace it. Contact your sales representative for a
new filter. If you continue to use the projector when its filter is damaged, dust and dirt
will enter the interior and this could cause the projector to stop working or break down.
