Also keep these considerations in mind:
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and under the projector. Do not set the projector on top of loose papers that could block the vents under the projector.
■Make sure the projector is within 6 feet (2 m) of a grounded electrical outlet or extension cord.
Try to place the projector directly in front of the center of the screen, facing it toward the screen squarely. If the projector isn’t positioned this way, the image will be “keystone” shaped, instead of square or rectangular.
If you place the projector below the level of the screen, you’ll have to tilt it up by extending the front adjustable foot, as described on page 39. This also causes the image to lose its rectangular shape. You can adjust the shape using the buttons on the projector (see page 39), or using the projector’s menu system (see page 61).
On the PowerLite 77c, the Auto Keystone feature corrects the distortion automatically. See page 62 for more information about Auto Keystone correction. If necessary, you can adjust the image shape manually as described on page 39.
