Projection distance
A ±5 % error in listed projection distances may occur.
When [SCREEN ADJUSTMENT] is used, distance is corrected to become smaller than the specified image size.

Formula for calculating the projection distance
To use a projected image size not listed in this manual, check the projected image size SD (m) and use the
respective formula to calculate the value.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
When calculating the value using image size designation (value in inches), multiply the value in inches by 0.0254
and substitute it into SD in the formula.
Aspect ratio 16:10 Aspect ratio 16:9 Aspect ratio 4:3
Projected image size
Height (SH)
= SD x 0.530 = SD x 0.490 = SD x 0.6
Projected image size
Width (SW)
= SD x 0.848 = SD x 0.872 = SD x 0.8
Projection distance (L) = 0.6892 x SD - 0.0474 = 0.7084 x SD - 0.0474 = 0.7802 x SD - 0.0474
Adjusting adjustable feet
Install the projector on a flat surface so that the front of the projector is parallel to the screen surface and the
projection screen is rectangular.
If the screen is tilted downward, extend the front adjustable feet so that the projected image becomes rectangular.
The adjustable feet can also be used to adjust the projector to be level when it is tilted in the horizontal direction.
Adjustable feet can be extended by turning them as shown in the figure. Turning them in the opposite direction will
return them to the original position.
Maximum adjustable range
Adjustable feet: 35 mm (1-3/8") each
Attention
f
Be careful not to block the intake/exhaust ports with your hands or any objects when adjusting the adjustable feet while the light source is
on. (
