1. Click on the << or >> boxes next to R_GAIN
and B_GAIN to make the video white.
(For 9300K color adjustment:
x = 0.283 ± 0.02,
y = 0.298 ± 0.02.)
Note: Do not touch the G_GAIN controls.
2. Check the ABL. If it is not within the
specifications (35 ± 1 ft-L), use the ABL
controls to adjust it.
3. Select COLOR FACTORY SAVE to save the
data.

1. Check whether the color coordinates of the
back raster satisfy the above spec.
If they do not, return to 6-4-2 (a) and readjust
all settings.
2. Display a full white pattern.
Note:
Do not touch the G_GAIN controls.
3. Adjust the Contrast Control on the monitor so
that the luminance of the video is about 5 ft-L.
4. Check whether the white coordinates of the
video meet the above coordinates spec.
5. Adjust the Contrast Control again so that the
luminance of the video is about 24 ft-L.
6. Check whether the white coordinates of the
video satisfies the above spec.
If they do not, return to 6-4-2 (a) and readjust
all settings.

Contrast:
1. Select COLOR CHANNEL 2 to control the
color for 6500K.
2. Adjust the luminance of the back raster to
between 0.4 to 0.5 ft-L using the G_CUT
controls.
Note: For 6500K adjustments you must not
change the Screen VR of the FBT. To do so
changes the 9300K setting values.
3. Click on the << or >> boxes next to R_CUT
and B_CUT to adjust the R-Bias to x = 0.313 ±
0.02 and the B-Bias to y = 0.329 ± 0.02.
