Adjusting 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 3.28 feet (1 m) from the 
projection screen.
•Position the projector to the required 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.
•Lens throw ratio: 1.2 ~ 2.13
•360 degree free orientation operation
