(3) DDC adjustment support command set.
* R/G/B GAIN max value : 80
12-5. Adjustment of White Balance
(For Manual adjustment)
-  Adjustment  mode  :  Two  modes  of  Cool  (Dynamic)  and
Warm(Mild).
(Medium data is automatically calibrated by the cool data)
-  Color  analyzer(CA110,  CA210)  should  be  used  in  the
calibrated ch by CS-1000.(PDP : CH10)
- Operate the zero-calibration of the CA-110 or CA-210, then
stick sensor to the module when adjusting.
-  For  manual  adjustment,  it  is  also  possible  by  the  following
sequence.
(1)  Select  RF  no  signal  by  pressing  “POWER  ON” key  on
remote  control  for  adjustment  then  operate  heat  run  more
than 15 minutes. 
(If not executed this step, the condition for W/B will be differ.)
(2) Changing to the av mode by pushing the input or front av
key.(av mode : av1 or av2 or av3)
(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 items
(Red/Green/Blue  Gain  and  Offset)  using 
D
/
(CH+/-)  key
on R/C.
(5) Adjust R Gain / B Gain using 
F
/
G
(VOL+/-) key on R/C.
(6)  Adjust  two  modes  of  Cool(Dynamic)  and  Warm(Mild)  as
below figure.
(Fix the one of R/G/B and change the others)
1. Push the one time the in-start key : Dynamic(Cool)
2. Push the two more the in-start key : Mild(Warm)
* Refer to the below case to know what value is fixed.
* CASE
- First adjust the coordinate much away from the target
value(x, y).
1) x, y > target
(1) Decrease the R, G. 
2) x, y <  target
(1) First decrease the B gain.
(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
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.
13. Input the Shipping Option Data
(1) Push the ADJ key in a Adjust Remote control.
(2)  Input  the  Option  Number  that  was  specified  in  the  BOM,
into the Shipping area.
(3) The work is finished, Push 
A
Key.
14. Default Value in Adjustment mode
(Default values maybe modified the module condition)
