Adjusting adjustable feet

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 front
adjustable feet. The adjustable feet can also be used to adjust the projector to be level when it is tilted in the
horizontal direction.
Adjustable feet can be extended by turning them as shown in the figure. Turning them in the opposite direction will
return them to the original position.
Attention
f Heated air is expelled from the air exhaust port while the lamp is lit. Do not touch the air exhaust port directly with your hand when adjusting
the adjustable feet. (x page 27)
