When using the projector with screen sizes not listed in the above charts, calculate the values according to the formulas.
L1: Minimum projection distance (m/ft)
L2: Maximum projection distance (m/ft)
H: Distance from the lens center to the bottom of the image (cm/in)
S: Adjustable range of image position (cm/in) See page 46.
χ : Picture diagonal size : 40''-300''
