Adjust the lamp optical axis in the order of Z axis → X and Y axes → Z axis. At that time, make sure
that the LCD value decreases at around each maximum point of X, Y and Z axes, and adjust each to
the maximum value. When the LCD value does not decrease at around the maximum value, there
may be a failure in the loading of lamp, or a failure in the equipment.
4. Perform the CSC adjustment. (Refer to Installation Manual.)
Before adjusting CSC, be sure to perform a reset.
