Installation
Adjust the Projector Position
When you select a position for the projector, consider the size and shape of your
screen, the location of your power outlets, and the distance between the projector
and the rest of your equipment. Follow these general guidelines:
• Position the projector on a flat surface at a right angle to the screen. The
projector (with the standard lens) must be at least 3 feet (0.9m) from the
projection screen.
• Position the projector to the desired distance from the screen. The distance
from the lens of the projector to the screen, the zoom setting, and the video
format determine the size of the projected image.
• For the fixed short lens, the image exits at a default angle. However, the lens
shift feature makes the image offset variable.
• 360 degree free orientation operation
