Basic Operation
If the lens is heavy or the projector is installed so that it is tilted, the lens may be tilted, resulting in the focus
becoming unbalanced.
In such a case, refer to the figure 4 and table below, and follow the procedure below to perform adjustment.
Adjustment procedure
z
1
Display the internal test pattern grid, and defocus the image.
2
Adjust the lens focus till one or more sides of the grid comes into focus. Note the appropriate screws
for the out-of-focus sides of the grid as described below.
3
Remove the lens cover and lens.
4
Loosen the locking screws for each of the adjustment screws
a
,
b
and
c
as needed, following the
indications in the example. The screws to be adjusted correspond to the out-of-focus sides of the
image.
Attention
Be careful because turning a screw more than twice to loosen it will result in the spring becoming detached
•
and the projector needing to be repaired.
Make adjustments in up to two places, and fully turn the screw clockwise in at least one place.
•
5
Reinstall the lens. The adjustment screws can be accessed through the lens flange.
6
Turn the adjustment screws (corresponding to the locking screws loosened in step 4) counterclockwise
slightly till the out-of-focus image sides are in focus. (Turning the screws counterclockwise moves the
lens bracket and tilts the lens toward the screen.)
7
Readjust the lens shift position with the remote if needed.

Refocus the image as in steps 1 and 2 above. Fine adjust the focus evenness as needed, as described in
step 6.
9
When adjustment is complete, remove the lens and then tighten the locking screws.
