Installing and Composition
13
1.Place the projector on a sturdy and horizontal surface with the PC or AV source.
2.Place the projector with 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. If this is so then the keystone adjustment may correct this (Refer to page 26.).
4.Connect the cables of the projector to a wall power socket and other connected sources.
