To focus the image, rotate the focus ring (Figure 10) until the 
image is clear. To zoom the image, rotate the zoom ring. This 
adjusts the image size without affecting focus.

The projector is equipped with a self-locking, quick-release eleva-
tor foot and button and a leveling knob (Figure 11).

To raise the projector:

Press and hold the elevator button (Figure 11).

Raise the projector to the height you want, then release the 
button to lock the elevator foot into position. If necessary, turn 
the leveling knob at the rear of the projector to adjust the 
angle of the projected image.
