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.
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” (
