PREPARATION 17 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 at an appropriate distance from the screen. The distance be- tween 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 image on the screen will be tilted and the image quality will be poor. If the screen image is crooked, use the Keystone function. (see page 26) 4 Connect the power cords of the projector and the connected devices to the wall outlet.
