Cautions on use

In order to get the picture quality

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

from indoor 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 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 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 hand.

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

onto the screen.

LCD Panel

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

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.
