Installing and Composition

1. Place the projector on a sturdy and horizontal surface with the PC or AV source.
2. The distance between the projector and the screen determines the actual size of the image.
3. Position the projector so that the lens is set at a right angle to the screen. If the projector is not set at a
right angle, the screen image will be crooked. Although, slight angles can be counteracted using the
Keystone adjustement. (Refer to page 25.)
4. Connect the power cable to the projector and the wall outlet after placing the projector in its desired
location.
