hand glass and check there is no effect on the right-hand area.

4. Press the upper and lower buttons simultaneously to set the LCD contrast back to normal.

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.
