Setting Up Your Projector 15
Adjusting the Height
The projector is equipped with 2 quick-release adjuster feet.
1. Lift the projector up and press
the adjuster button to release
the adjuster. The adjuster will
drop into position and be
locked.
2. Screw the rear adjuster feet to
fine-tune the projection angle.
If the screen and the projector are not per-
pendicular to each other, the projected
image becomes vertically trapezoidal. To
correct this situation, adjust the value of
Keystone in the Display menu, on the projec-
tor control panel or on the remote control.

size (see the table on the next page).
