SH Projected image height L3 Screen to projector front end
SW Projected image width 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 reective
surface*)
A2
Bottom edge of the screen to the bottom of the
projector
L2 Screen to lens front end
* The mirror reective surface is inside the xed-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 specic
projector model. Congurations may vary with the model.
z
After setting the lens position using the function on the projector, the lens position can be adjusted within the
adjustment range described in "Adjustment range by the lens position shift (optical shift)"
(
Page 12).
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 conned space, a ventilation and/or air conditioning system is required.
Exhaust heat may accumulate when the ventilation is not sufcient triggering the protection circuit of the projector.
