Precautions during use
Burning-in of D-ILA device
Do not allow the same still picture to be projected for
a long time or an abnormally bright video image to be
projected.
Do not project still images with a high brightness or
high contrast on the screen for a long time. This video
image could be burnt into the D-ILA device.
Pay special attention when projecting video games and
computer program images.
Motion images such as normal video playback images
do not pose the burning-in problem.
Viewing conditions – brightness of
room
Shield the screen from direct sunlight or bright lights,
such as by using a curtain. Images are best projected
in a darkened room.
Do not view the screen for prolonged hours. Looking at
a screen continually for a prolonged time is tiring to the
eyes. Allow your eyes to rest at intervals.
Do not use this unit if the image is flickering due to the
installation conditions or environment.

or oily smoke. This may cause the unit to malfunction.

in use, the ceiling may reach a temperature higher than
anticipated, leading to malfunction of the unit.
