Epson PowerLite 76c Projector Image Size and Projection Distance The distance between the projector and the screen determines the basic size of the projected image, as shown below. The diagram shows approximately how big your image will be, based on where you set up the projector. Because other adjustments- such as those made with the Resize and keystone buttons-also affect the size of the image, the numbers shown in the illustration should be considered as general guidelines, not exact measurements. Distance from projector to screen (ft.) 29.5(Wide)-35.4(Tele) ft. 19.6-23.6 (in.) 9.8-11.7 7.8-9.4 5.8-7.0 4.8-5.8 3.8-4.6 2.8-3.4 Turning On the Projector Make sure your projector and other equipment are set up and connected correctly. Then turn on your projector, as described below. If you turn on your connected computer or video equipment before starting the projector, the projector automatically detects and displays the image source. If you turn on the projector first, or have multiple pieces of connected equipment, you may have to select the image source manually. See "Selecting the Image Source" on page 6. Follow these steps to plug in and turn on the projector: 1. Remove the lens cap. Caution: Do not use the projector with the lens cap in place. The heat generated by the lamp can damage the cap. Use the formulas given below to either find out how large your image will be when you know the distance from the projector to the screen, or to find out how far from the screen to place the projector when you want an image of a certain size. Since the size of the image can be changed by rotating the zoom ring, formulas are given for both the minimum and maximum sizes. To determine the diagonal size (inches) of an image when you know the projection distance (feet): Wide: Maximum diagonal size (inches) = 10.126246 × distance (feet) + 1.166113 Tele: Maximum diagonal size (inches) = 8.443213 × distance (feet) + 0.916898 To determine the projection distance (feet) when you know the diagonal size (inches) of the screen image: Wide: Maximum projection distance (feet) = 0.09875 × diagonal size (inches) - 0.11516 Tele: Maximum projection distance (feet) = 0.11844 × diagonal size (inches) - 0.1086 2. Connect one end of the power cord to the projector's power inlet. Then connect the other end to an electrical outlet. The Power light on top of the projector turns orange. 3. Turn on your computer or video source if they are not on already. 4. Press the P Power button on top of the projector or on the remote control. Power button 4 - Epson PowerLite 76c Projector 9/05
