z

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 

 

z

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 flow 

between the projector and the screen.

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 (

 page 63) for an hour or more. Note that it may not be possible to 

completely remove the after-image.

J

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.
