• There is an error of ע3% in the formula above.
• Values with a minus (מ) sign indicate the distance of the lens center below the bottom of the screen.
• The values do not match up when applying the formula in *1 to *9 above. However, this is not a calculation error.
• For optimum focus, the recommended projection distance (L) is from 3Ј 9Љ (1.15m) to 32Ј 10Љ (10.0m).
