6-5. Adjustment of White Balance for
Manual Adjustment
(1) Adjustment mode: Two modes of Cool (Dynamic) and
Warm(Mild)
(Medium data is automatically calibrated by the cool data)
(Medium data is automatically calibrated by the cool data)
(2) Color analyzer(CA110) should be used in the calibrated ch
by CS-1000(PDP : CH10)
(3) Operate the zero-calibration of the CA-110 then stick
sensor to the module when adjusting.
(4) For manual adjustment, it is also possible by the following
sequence
1) Select white pattern of heat-run by pressing “POWER
ON” key on remote control for adjustment then operate
heat run longer than 15 minutes.
(If not executed this step, the condition for W/B will be
differ )
heat run longer than 15 minutes.
(If not executed this step, the condition for W/B will be

2) Changing to the av mode by remote control.(av mode :
av1 or av2)
3) Display the internal pattern of the VCT-Pro IC by
pushing the IN-START.
4) Stick sensor to center of the screen and select each

Refer to the below case to know what value is fixed.
[CASE]
First adjust the coordinate much away from the target
value (x, y).
First adjust the coordinate much away from the target
value (x, y).
1. x, y > target
Decrease the R, G.
2. x, y < target
1) First decrease the B gain,
2) Decrease the one of the others.
2) Decrease the one of the others.
- In case of decreasing the x, decreasing the R : fix G
- In case of decreasing the y , decreasing the G : fix R
- In case of decreasing the y , decreasing the G : fix R
3. x > target , y < target
1) First decrease B, so make y a little more than the
target.
2) Adjust x value by decreasing the R
4. x < target , y > target
1) First decrease B, so make x a little more than the
target.
2) Adjust x value by decreasing the G
7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C
