Positioning The Projector - LG AF115 Owner's Manual

Installing and Composition

Positioning the Projector

1. Place the projector on a sturdy and horizontal surface.
2. Place the projector the desired distance 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 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 loca-
tion.
