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.
Auto-adjusting the image
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.
The current source information will be displayed in the corner of the
screen for 3 seconds.
The screen will be blank while AUTO is functioning.
Fine-tuning the image size and clarity
1. Adjust the projected image to the size that you need using the
zoom ring.
2. Then sharpen the image by rotating the focus ring.

the lamp may cause damage to
your eyes.
