Cautions on use

To get a good picture quality r

Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor f

lamps from shining onto the screen.

Depending on where the projector is used, heated air from an exhaust port or warm or cold air from an air conditioner can f

cause a shimmering effect on screen.

Avoid use in locations where exhaust or streams of air from projector, other devices and air conditioners ow between the

projector and the screen.

The lens of projector is affected by the heat from the luminous source. Because of this, the focusing may not be stable right f

after the power is turned on. Focusing is stabled after projecting image for 30 minutes and longer.

Do not touch the surface of the projector lens with your bare hands. r

If the surface of the projection lens becomes dirty from ngerprints or anything else, this will be magnied and projected onto

the screen.

Attach the supplied lens cap to the projection lens when you do not use the projector.

LCD Panel r

The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision

technology, some of the pixels on the projected image may be missing or constantly lit. Please note that this is not a

malfunction.

Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all white

screen in the test pattern for an hour or more.

Optical components r

Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke will reduce the

service life of the optical components, such as the LCD panel and polarizing plate, and may necessitate their replacement

within less than one year of use. For details, consult your dealer.

Lamp r

The luminous source of the projector is a mercury lamp with high internal pressure.

A high pressure mercury lamp has following characteristics.

The brightness of the lamp will decrease by duration of usage. f

The lamp may burst with sound or shorten life by shock or chipping. f

The life of the lamp varies greatly depending on individual specicities and usage conditions. In particular, continuous use f

over 12 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.

In rare cases, the lamp burst shortly after the projection. f

The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit f

consistently. (“When to replace the lamp unit” (

page 97))

If the lamp bursts, gas contained inside of the lamp is released in a form of smoke. f

It is recommended to store replacement lamps for contingency. f

It is recommended to have authorized engineer or your dealer replace the lamp unit. f
