Make sure that the side vent is not blocked. Plug the power cord

into a standard 120V AC outlet. Push the power button in to turn the

projector on. Place a transparency on the stage. If the fourth element

lens is in place, an enlarged view of the transparency will be pro¬

fourth element lens towards the projector's mast and away from the
