Install the projector on a flat surface so that the front of the projector is parallel to the screen surface and the projection screen is rectangular.
If the screen is tilted downward, the projection screen can be adjusted to be rectangular by adjusting the adjustable feet. The adjustable feet 

can also be used to adjust the projector to be level when it is tilted in a horizontal direction.
Extend the adjustable feet by rotating in the direction shown in the figure and retract by rotating in the opposite direction.
