36 Operation
Adjusting the projected picture
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 picture distortion" on
page 37 for details.
Auto-adjusting the picture
In some cases, you may need to optimize the
picture quality. To do this, press AUTO on 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.
Fine-tuning the picture size and clarity
1. Adjust the projected picture to the size that
you need using the zoom ring.
2. Then sharpen the picture by rotating the
focus ring.
