The Shortest Distance/Longest Distance is adjusted by rotating the zoom ring using
the zoom function.

The projection distance for each screen size is just a reference, and there is about
±5 % deviation.
Projection Distance per Screen Size
1 Place the projector on a sturdy, level surface, together with the computer or audio/
video source.
2 Place the projector at an appropriate distance from the screen. The distance be-
tween the projector and the screen determines the actual size of the image.
3 Position the projector so that the lens is perpendicular to the screen. If the lens is not
perpendicular to the screen, the projected image will look distorted. To correct the
distortion, use the Keystone function. (See 25 page)
4 Connect the power cords of the projector and connected devices to the wall outlet.
