Image Adjustments
Focus adjustment
1. Focus the image by rotating the focus ring in a clockwise direction (Picture 1) and then again
slowing in a counter clockwise rotation. It is best to focus the projector using a still image.
2. Turn the tuning focal ring to adjust the image size.
Keystone
Manually correct distorted images resulting from an angled projection. The Keystone correction knob
is shown in Picture 3. The maximum amplitude is ± 15 degrees. If the keystone correction knob is set
at its highest and does not eliminate distortion, shorten the distance between the projector and the
screen. The projection angle can be changed by rotating the base plate angle adjustment Lift bracket.
