Adjusting the projection angle

The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot.
These adjusters change the image height and projection angle. To adjust the projector:
1. Press the quick-release button and lift the
front of the projector. Once the image is
positioned where you want it, release the
quick-release button to lock the foot in
position.
2. Screw the rear adjuster foot to fine tune
the horizontal angle.
To retract the foot, hold up the projector while
pressing the quick-release button, then slowly lower the projector. Screw the rear
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
• Do not look into the lens while the lamp is on. The strong light from the lamp
may cause damage to your eyes.
• Be careful when you press the adjuster button as it is close to the exhaust vent
where hot air comes from.
