•There is an error of 3% in the formula above.

•Values with a minus () 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 3 9 (1.15m) to 32 10 (10.0m).
