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 3 and table below, and follow the procedure below to perform adjustment.
Adjustment procedure
Q
Display the internal test pattern grid, and defocus the image.
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.
Loosen the locking screws for each of the adjustment screws , and as needed, following the
indications in the example. The screws to be adjusted correspond to the out-of-focus sides of the
image.
Attention
Make adjustments in up to two places, and fully turn the screw clockwise in at least one place. z
Turn the adjustment screws (corresponding to the locking screws loosened in step 3)
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.)
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 4.
When adjustment is complete, tighten the locking screws.
Adjust the Focus.
