Setting-up dimensions which are not given in the above table can be calculated using the formulas below.

If the screen size (diagonal) is SD (m), then the following formula is used to calculate the projection distance for the wide lens position (LW) and the projection distance for the telephoto lens position (LT).

LW=0.0407xSD/0.0254-0.080

LT=0.0538xSD/0.0254-0.0774

For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.

LW=0.0443xSD/0.0254-0.080

LT=0.0586xSD/0.0254-0.0774

NOTE:

BThe dimensions in the table above and the values obtained from the above formulas may contain slight errors.

BIf you use the projection distance for the 16:9 screen, the 4:3 projection image overflows the screen at the top and

bottom.

BIf you set up the projector vertically, it may cause to

damage the projector.

BIt is recommended that you set up the projector in a place that is tilted at less than ±35°. Setting up the projector in places that are tilted at more than ±35° may cause malfunctions.

Make sure that enough space is kept for the air outlet port.
