Overview 1 Chapter

projector. Be aware that room heat rises to the ceiling; check that the temperature near the installation location is not excessive.

•Install the projector on the floor or hang it from the ceiling. Any other installation causes a malfunction such as color irregularity or a shorten lamp life.

•Do not install the unit in a location near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust or humidity, mechanical vibration or shock.

•To avoid moisture condensation, do not install the unit in a location where the temperature may rise rapidly.

For maximum protection, repack your unit as it was originally packed at the factory.

On “stuck” pixels on a LCD screen

The LCD panel fitted to this unit is manufactured with high precision technology. Thus a very small proportion of pixels may be “stuck”, either always off (black), always on (red, green, or blue), or flashing. In addition, over a long period of use, because of the physical characteristics of the liquid crystal display, such “stuck” pixels may appear spontaneously. These problems are not a malfunction.

On illumination

•To obtain the best picture, the front of the screen should not be exposed to direct lighting or sunlight.

•Ceiling-mounted spot lighting is recommended. Use a cover over fluorescent lamps to avoid lowering the contrast ratio.

•Cover any windows that face the screen with opaque draperies.

•It is desirable to install the projector in a room where floor and walls are not of light-reflecting material. If the floor and walls are of reflecting material, it is recommended that the carpet and wall paper be changed to a dark color.

On preventing internal heat build-up

After turning off the power, the cooling fan runs for about 10 minutes while the STATUS LAMP indicator flashes green.

Caution

The projector is equipped with ventilation holes (intake) at the front, upper side and right side, and ventilation holes (exhaust) at the rear and upper side.

Do not block or place anything near these holes, or internal heat build-up may occur, causing picture degradation or damage to the projector.

On cleaning

•To keep the cabinet looking new, periodically clean it with a soft cloth. Stubborn stains may be removed with a cloth lightly dampened with a mild detergent solution. Never use strong solvents, such as thinner, benzene, or abrasive cleansers, since these will damage the cabinet.

•Avoid touching the lens. To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent solution, or thinner.

On repacking

Save the original shipping carton and packing material; they will come in handy if you ever have to ship your unit.

On prohibiting continuous lighting

Continuously lighting the Xenon lamp for 24 hours will reduce approximately half of its lamp life. Be sure to off the lamp for an hour or more after continuously lighting for 24 hours.

To light the lamp continuously for 24 hours, it is recommended to use the lamps alternately. To use the lamps alternately, select “User-Defined” in “Single” (page

31)under “LAMP SELECT” in the INSTALLATION window and set the time.
