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, extend the front adjustable feet so that the projected image becomes rectangular.
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 Be careful not to block the intake/exhaust ports with your hands or any objects when adjusting the adjustable feet while the light source is
on. (x page 30)

Formula for distance between projector and
Projection distance
(L1) formula
= 0.310 x SD + 0.020 = 0.166 x SH - 0.128
= 0.337 x SD + 0.020 = 0.222 x SH - 0.128
= 0.310 x SD + 0.020
= 0.337 x SD + 0.020 = 0.275 x SH - 0.128
