If
you are projecting from a table or other flat surface, and the
image is too high or low, you can adjust the image height using the
projector's adjustable feet. Make sure the feet have been
installed.
Caution:
Tilting the projector will distort the image
shape and may cause difficulty focusing the image. For
interactive use, make sure the projector is not tilted an an angle
of more than ± 3º vertically or horizontally.
