Removing And Closing Lens Cover; Reducing Image Distortion - DigiTech AP4006 Instruction Manual

REMOVING AND CLOSING THE LENS COVER:

REDUCING IMAGE DISTORTION:

It is recommended to move the projector as close to center of screen.
Adjust the focus by turning the knob while
observing the image pixels near the center
of the screen. Optimal focus is obtained
when the pixels are clearly visible.
Depending on the projected screen size,
the focus near the screen edges may be
less sharp than the screen center.
Keystone image is created when the
projector beam is projected to the screen
in an angle.
Keystone correction will restore the
distorted image to a rectangular or square
shape.
