Cautions on use
In order to get the picture quality
J
Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light
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 lens of projector is affected by the heat from the luminous source. Because of this, the focusing may not
z
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.
J
If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected
onto the screen.
LCD Panel
J
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
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.
