L1
*1
Projection distance (distance from the mirror reflection surface
*2
to the screen)
L2
Distance from the front end of the projection lens to the screen
L3
Distance from the front surface of the projector to the screen
L4
Distance from the back surface of the projector to the screen
A1
*1
Distance from the top surface of the projector to the bottom edge of the screen
A2
Distance from the installation surface of the projector to the screen (adjustable feet at lowest position)
*1
For details of calculating values, refer to “Formula for calculating the projection distance per projection lens” (
x
page 48).
*2 The mirror reflection surface cannot be seen from the outside, because it is located inside the Fixed-focus Lens.
(Unit: m)
Distance from the projector
to the screen
Formula
ET-D75LE95
ET-D75LE90
L2
= L1 + 0.029
= L1 + 0.029
L3
= L1 - 0.292
= L1 - 0.277
L4
= L1 - 1.017
= L1 - 1.002
A2
= A1 + 0.324
= A1 + 0.324
Attention
f
The dimension of L4 is not the distance between the back surface of the projector and the wall, but the distance between the back surface of
the projector and the screen surface. Install the projector with 500 mm (19-11/16") or larger space between the back surface of the projector
and the wall or any object so that the ventilation is not obstructed.
f
When installing the projector in a confined space, provide air conditioning or ventilation separately. Exhaust heat may accumulate when the
ventilation is not enough, triggering the protection circuit of the projector.
Note
f
For the adjustment range of the projected image position with the lens shift, refer to “Lens shift range” (
x
page 77).
