Adjusting the projected image

Adjusting the projection angle
The projector is equipped with two front adjuster foots. These adjusters change the image
height and projection angle. To adjust the projector:
1. Screw the front adjuster foot. Once the image
is positioned where you want it.
2. Screw the adjuster foot to fine tune the
horizontal angle.
To retract the foot. Screw the adjuster foot in a
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

damage to your eyes.

the projector or remote control. Within 3 seconds, the built-in Intelligent Auto
Adjustment function will re-adjust the values of Frequency and Clock to provide the best
picture quality.
