EPSON PowerLite 5300/7200/7300 Projector To determine the projection distance when you know the diagonal size of the screen image: t Inches: Maximum projection distance = (2.1949 × diagonal size) − 2.5044 Minimum projection distance = (1.6328 × diagonal size) − 2.4923 t Centimeters: Maximum projection distance = (2.1949 × diagonal size) − 6.3612 Minimum projection distance = (1.6328 × diagonal size) − 6.3304 For example, here are the measurements for three installations: Image size (diagonal) Horizontal distance from projector to screen Minimum Maximum 300 inches* (762 cm) 487.3 inches (12.4 m) 656.0 inches (16.7 m) 200 inches (508 cm) 324.1 inches (8.2 m) 436.5 inches (11.1 m) 100 inches (254 cm) 160.8 inches (4.1 m) 217.1 inches (5.5 m) * For an image size of 300 inches, the projector may be up to 54 feet away from the screen, depending on the setting of the zoom ring. Long Throw Zoom Lens Calculations If you are using the optional long throw zoom lens, use the following formulas instead: To determine the minimum and maximum diagonal size of an image when you know the projection distance: t Inches: Maximum diagonal size = (0.4742 × projection distance) + 3.2489 Minimum diagonal size = (0.2849 × projection distance) + 1.8968 t Centimeters: Maximum diagonal size = (1.2045 × projection distance) + 8.2521 Minimum diagonal size = (0.7236 × projection distance) + 4.8179 To determine the projection distance when you know the diagonal size of the screen image: t Inches: Maximum projection distance = (3.5094 × diagonal size) − 6.6568 Minimum projection distance = (2.1090 × diagonal size) − 6.8519 t Centimeters: Maximum projection distance = (8.9139 × diagonal size) − 16.9083 Minimum projection distance = (5.3569 × diagonal size) − 17.4038 Projector Status Lights The status lights on top of the projector tell you the projector's operating status. power light temperature light projection lamp light Caution: A red light warns you if a serious problem occurs.
