Formula for calculating the projection distance per projection lens
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 projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches 
by 0.0254 and substitute it into SD in the formula for calculating the p\
rojection distance.For PT

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, the projection screen can be adjusted \
to be rectangular by adjusting the front 
adjustable feet. 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.
Adjustable range
Adjustable feet: Approx. 12 mm (15/32) each
Attention
 f Heated air is expelled from the air exhaust port while the lamp is lit. Do not touch the air exhaust port directly with your hand when adjusting 
the adjustable feet. (
