You can adjust the size of image within zoom range by manipulating the Zoom Knob. Focus the picture on the screen using the Focus Ring. If your product is installed at a location out of the specified projection distance (refer to Screen Size and Projection Distance), the focus cannot be adjusted correctly. Leveling with Adjustable Feet For level placing of the projector, adjust the Adjustable Feet of the projector. You may adjust the level of the projector up to 12 mm (average 3.4°) degrees. Depending on the position of the projector, Keystone distortion of image may appear. Screen Size and Projection Distance Install the projector on a flat, even surface and level the projector using the adjustable feet to realize optimal picture quality. If images are not clear, adjust them using the Zoom Knob or Focus Ring, or move the projector forward and backward.
