Adjusting the projected image

Adjusting the projection angle
The projector is equipped with 1 front adjuster foot and 1 rear adjuster foot. 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 rear adjuster foot to fine tune the
horizontal angle.
To retract the foot. Screw the front and 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
"Correcting 2D Keystone" on page 26

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.

Adjustment function will re-adjust the values of Frequency and Clock to provide the best
picture quality.
