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, 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 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.
