Adjusting the projected image

Adjusting the projection angle

The projector is equipped with 2 quick-release adjuster feet. These adjusters change the picture height and projection angle.

To adjust the projector, slightly lift the front of the projector and press and hold the quick-release buttons on the both sides near bottom until the picture is positioned where you want it.

To retract the foot, hold up the front of the projector while pressing the quick-release buttons, then slowly lower the projector.

If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected picture becomes trapezoidal. To correct this situation, see "Correcting keystone" on page 28 for details.
