8-ENGLISH
The dimensional relationship between the screen and the projector is shown below.
SH
Height of the projection area
SW
Width of the projection area
SD
Diagonal length of the projection area
L1
Projection distance (screen to mirror reflecting surface)
L2
Screen to lens front end
L3
Screen to projector front end
L4
Screen to projector rear end
A1
Bottom edge of the screen to the top of the projector
A2
Bottom edge of the screen to the bottom of the projector
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 adjusting the lens position on the projector or using the lens shift gauge, lens shift adjustments are
possible within the range where the projector will not interfere with the edges of the projected image.
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.
