PREPARATION
ProjectionDistanceperScreenSize
1 Place the projector on a sturdy, level surface, together with the PC or
audio/video source.
2 Place the projector an appropriate distance away from the screen. The
distance between the projector and the screen determines the actual
size of the image.
3 Position the projector so that the lens is at a right angle to the screen.
If the projector is not at a right angle, the projected image will look
distorted. To correct the distortion, use the keystone function.
(See page 33.)
4 Connect the power cord of the projector and the connected device to
the wall outlet.
