The indications of this illustration are premised on aligning the projected image size and position to the full screen.

L4
Screen to projector rear end
SD
Diagonal length of the projected image
A1
Bottom edge of the screen to the top of the
projector
L1
Projection distance
(from screen to mirror reflective
surface*)
A2
Bottom edge of the screen to the bottom of the
projector
L2
Screen to lens front end
* The mirror reflective surface is inside the fixed-focus lens, and is not visible from the outside.
Note
z
The illustrations of projectors in this manual are for informational purposes only and do not represent a specific
projector model. Configurations may vary with the model.
z
After setting the lens position using the function on the projector or using the lens shift gauge, the lens position
can be adjusted within the adjustment range noted in "Adjustment range by the lens position shift (optical
shift)" (
Page 11).
Then dimensions A1 and A2 will change according to lens shift amount.
z
Dimension L4 is the distance from the projector rear panel to the screen.
z
Dimension A2 is the distance from the bottom edge of the screen to the bottom of the adjustable projector legs
(with the legs fully screwed in).
Attention
z
Dimension L4 is not the distance from the projector rear panel to a wall, but the distance from the projector
rear panel to the screen. Provide at least 500 mm (19-11/16") of ventilation space between the projector rear
panel and a wall or other object.
When placing the projector in a confined space, a ventilation and/or air conditioning system is required.
Exhaust heat may accumulate when the ventilation is not sufficient triggering the protection circuit of the projector.
