Cautions on use

f
In order to view a beautiful image in higher contrast, prepare an appropriate environment. 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.

The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in the period
just after switching on the power. The focus stabilizes when an image is projected continuously for 30 minutes or more.

Do not touch the surface of the projection lens with your bare hands.
If the surface of the projection lens becomes dirty from ngerprints or anything else, this will be magnied and projected onto
the screen.

The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that
such phenomena does not indicate malfunction.

Directing a high-power laser beam onto the lens surface can damage the DLP chips.
