Projecting an Image (Basic Operation) Zoom Use the ZOOM (+) or (−) button on the projector cabinet to zoom in or out. • The zoom is not available on the separately sold NP16FL (PX750U) and NP06FL (PX700W/PX800X) lens. Adjusting the Tilt Feet • Turn the left and right tilt feet on the right, left, and rear to adjust. The tilt feet lengthen and shorten when turned. The height of the projected image is adjusted by turning the left and right tilt feet. If the projected image is tilted, turn one of the tilt feet to adjust the image so that it is level. - If the projected image is distorted, see "2-6 Correcting Keystone Distortion" (→ page 26). - The tilt feet can be used to tilt +/− 50 mm/1.97" (6.75°), −9 mm/0.35" (1.2°). Up Down Tilt foot CAUTION The rear vents of the projector may become heated during normal projector operation. Use caution when adjusting the tilt foot on the rear side. NOTE: • Do not lengthen the tilt feet on the right and left any more than 50 mm/1.97"and the tilt foot on the rear any more than 9 mm/0.35" on the rear. The force of doing so may cause the rear foot to come off, resulting in damage to the projector. • Do not use the tilt feet for any purpose other than adjusting the projector's projection angle. Handling the tilt feet improperly, such as carrying the projector by grasping the tilt feet or hooking it onto a wall using the tilt feet, could damage the projector. 25
