16 PREPARATION
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. If the screen
image is crooked, use the Keystone function. (See page 23.)
4
Connect the power cords of the projector and the connected devices to the wall
outlet.

±5 % deviation.
