Setting Up Your Projector 16
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.

Place the projector at the required distance from the screen according to the required picture
size (see the table on the next page).
