Cautions on use
rTo get a good picture quality
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 projection surface to prevent outside light or light from indoor lamps from shining
onto the projection surface.
f The projection lens of the projector 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 will stabilize after projection for more than 30 minutes has elapsed.
rDo not touch the surface of the projection lens with your bare hands.
The finger print or dirt on the projection lens surface may be projected enlarged to the projection surface.
rDLP chips
f The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that
such phenomenon does not indicate malfunction.
f Directing a high-power laser beam onto the projection lens surface can damage the DLP chip.
rLight source
Laser is used as the light source of the projector, and it has the following characteristics.
f The luminance of the light source will decrease by duration of usage.
The time of usage for the luminance of the light source to become half is approximately 20 000 hours. 20 000 hours is the
estimated duration, and it varies depending on individual differences and usage conditions.
If the light source goes off or the brightness reduces noticeably, ask your dealer about replacement of the light source unit.
rComputer and external device connections
When connecting a computer or an external device, follow the instructions of this manual, including the use of power cords and
shielded cables.
Disposal
To dispose of the product, ask your local authorities or dealer for correct methods of disposal.
