[Adjustment procedure]

1) Send the "adjustment process" code using the remote control.

2)Set the point 6 to the specified gradation, specify the strongest color as the fixed color, and adjust the RGB so that it becomes the standard value through negative adjustment. Then compare the R and G values; based on the result, calculate the Ye value in the following conditions.

R > G: Ye = G x 1.05

R < G: Ye = R x 1.05

*If the Ye value exceeds the initial value (input gradation x 4), it is rounded to that value or less.

3)Set the point 5 to the specified gradation, set the G correction value (692 x G value of point 6/916) (fractions rounded off) and the Ye correction value (692 x Ye value of

point 6/916) (fractions rounded off), and adjust the RB so that it becomes the stan- dard value.

4)Set the point 4 to the specified gradation, set the G correction value (532 x G value of point 6/916) (fractions rounded off) and the Ye correction value (532 x Ye value of

point 6/916) (fractions rounded off), and adjust the RB so that it becomes the stan- dard value.

5)Set the point 3 to the specified gradation, set the G correction value (464 x G value of point 6/916) (fractions rounded off) and the Ye correction value (464 x Ye value of

point 6/916) (fractions rounded off), and adjust the RB so that it becomes the stan- dard value.

6)Set the point 2 to the specified gradation, set the G correction value (296 x G value of point 6/916) (fractions rounded off) and the Ye correction value (296 x Ye value of

point 6/916) (fractions rounded off), and adjust the RB pattern so that it becomes the standard value.

7)Set the point 1 to the specified gradation, set the G correction value (180 x G value of point 6/916) (fractions rounded off) and the Ye correction value (180 x Ye value of

point 6/916) (fractions rounded off), and adjust the RB so that it becomes the stan- dard value.

8)Write the adjustment value by the MSET0003 command and turn off the AC power.

*RGB initial value of point 6: Set gradation 916

*RGB initial value of points 1 to 5: G correction value of each point

(At each point, make adjustment so that the remainder of the RGB adjustment value/ 4 is equal.)
