5. Rotate the R-axis through one full rotation and confirm that there is no position where

the variation in the grayscale values (GR and GL) is extreme. If the grayscale value is

too big, check the fluorescent status. If it is dirty, clean or replace it as necessary.

6. Rotate the R-axis by hand to find the positions where the grayscale values (GR and

GL) are maximized and minimized. Check that the minimum and maximum grayscale

values are within the tolerance of 120~160 (target: 120). Also check that the current

value is 24mA or less.

7. If the grayscale values are not within the target values, adjust them as shown below.

8. Press the lower button to display “CURRENT UP” or “CURRENT DOWN”. When

raising the value, display “CURRENT UP” and press the lower button to adjust the

value. When lowering the value, display “CURRENT DOWN” and press the lower

button to adjust the value.
