Projection Distance per Screen Size
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.
4
Connect the power cord of the projector and the connected device to the wall
outlet.
