Setup A, manuaily rotate Vg2 pot-meter on LOT until
brightness reaches 100 scale.
Setup A, adjust RGB cut-off (I'C) for all colors at 100 7
scale, 9300 mode.
(x=0.283, y=0.297, Y=0.10
0.05FL)
Setup B, adjust RGB gain (1'C) for all colors at 100 2 scale,
9300 mode. (x=0.283, y=0.297, Y=41
0.5 FL)
Repeat 5.3.2, 5.3.3 (RGB cut-off and gain) to get both low
and high 9300 scales at 100. (0.10FL 0.05FL for low
scale; 41FL
1FL for high scale. x/y tolerance 0.005)
Setup C, adjust RGB cut-off (I'C) for all colors at 100 7
scale, 6500 mode. {x=0.313, y=0.329, Y=0.10FL
0.05FL)
Setup D, adjust RGB gain (IC) for all colors at 100 2
scale, 6500 mode.
(X=0.313, y=0.329, Y=36FL + 1FL)
Repeat 5.3.5, 5.3.6 (RGB cut-off and gain) to get both low
and high 6500 scales at 100. (0.10FL 0.05FL for tow scale:
36FL
1FLfor high scale. x/y tolerance 0.005)
Setup E, adjust RGB cut-off (°C) for all colors at 100 7
scale, sRGB mode.
(x=0.313, y=0.329, Y=0.10FL
0.05FL)(same values as

Setup G, adjust ABL (!'C) for 30FL 0.5FL, 9300 mode.
The above alignment method may be changed, as long as
the final results are the same.
(The above method has least amount of adjustment and
iteration steps.}
