Epson PowerLite 830p Use the Zoom buttons on the projector or remote to reduce or enlarge the image. Press the W button on the projector or the top zoom button on the remote to increase the size, or the T button on the projector or bottom zoom button on the remote to decrease it. Adjusting the Image Shape In most cases, you can maintain a rectangular image by placing the projector directly in front of the center of the screen with the base of the lens level with the bottom of the screen. Even if the projector is slightly tilted (within a range of 45° up or down), the projector's automatic keystone correction function detects and corrects vertical keystone distortion. Focus Zoom If the image still isn't large enough, you may need to move the projector farther away from the screen. You can also use the E-Zoom buttons on the remote control to zoom in on a portion of the image. Adjusting the Height of Your Image If the image is too low on the screen, you can raise it by adjusting the front foot: 1. Stand behind the projector. Press up on the blue foot release lever and lift the front of the projector. 2. Once the image is positioned where you want it, release the lever to lock the foot in position. 3. If necessary, you can fine-tune the height by turning the projector's rear feet. Projector tilted up Corrected image Projector tilted down It takes about one second after projection starts for the image to be corrected. During this time, a vertical keystone correction gauge appears on the screen. If your image is still distorted, you can correct it using either of these methods: ❏ If the image has two parallel sides but is wider on the top, bottom, left, or right, you can correct it using the Keystone buttons on the projector's control panel or the Keystone menu (see the next section). Keystone correction ❏ If the image has no parallel sides, you can adjust its shape using Quick Corner™ (see page 8). Keystone correction You cannot use both keystone correction and Quick Corner at the same time. Quick Corner correction Using Keystone Correction To adjust your image when it is wider on one side, do the following: ❏ Look at the shapes of the icons on the projector's four keystone buttons. Press the button whose icon is the opposite of the shape of your screen image. Continue pressing the button until you are satisfied with the shape of the image. Projector foot Raising the projector causes the image to distort or "keystone," but you can manually correct the shape as described in the next section. 10/04 Epson PowerLite 830p - 7
