Adjusting the projected image

The projector is equipped with 2 adjuster feet. These adjusters change the image height.
To adjust the projector:
• Screw the adjuster feet to adjust the image
height.
• To retract the feet, screw the adjuster feet in
reverse direction.
If the projector is not placed on a flat surface or
the screen and the projector are not
perpendicular to each other, the projected image
becomes trapezoidal. To correct this situation, see
"Correcting keystone" on page 30
