Positioning The Projector - LG CF181D 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 deter-
mines 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. The keystone adjustment may correct this (Refer to page 25.).
4.Once you have positioned the projector, connect the power and any input devices.
