Basic operations (Continued)
Precautions
•Lamp characteristics may rarely cause the brightness to fluctuate slightly.
•The LCD panel is made using extremely advanced 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 technology and are not malfunctions.
Notes
•A lamp is 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.53 , any resolutions not supported by this projector (XGA for X3131/X3241, WXGA for WX3131) will be expanded or shrunk, which will affect image quality slightly. To view
•With some models of computer having LCD displays or the like, 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.
•If no signal is being input from the connected equipment or signal input is stopped while projecting, the “No signal” message will appear.
•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.
•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. We recommend regular and thorough cleaning of the air filter p.47 .
•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.
