5-6. Adjustment Color Temperature
(White balance)
(1) Using Instruments
1) Color Analyzer: CA-210 (CH 9)
- Using  LCD  color  temperature,  Color  Analyzer  (CA-
210)  must  use  CH  9,  which  Matrix  compensated
(White,  Red,  Green,  Blue  compensation)  with  CS-
2100. See the Coordination bellowed one. 
2) Auto-adjustment  Equipment  (It  needs  when  Auto-
adjustment  –  It  is  availed  communicate  with  RS-232C  :
Baud rate: 115200) 
3) Video  Signal  Generator  MSPG-925F  720p,  216Gray
(Model: 217, Pattern 78)
(2) Connection Diagram (Auto Adjustment)
1) Using Inner Pattern
2) Using HDMI input
(3) White Balance Adjustment 
- If you can’t adjust with inner pattern, then you can adjust
it using HDMI pattern. You can select option at “Ez-Adjust
Menu  –  7.  White  Balance”  there  items  “NONE,  INNER,
HDMI”. It is normally setting at inner basically. If you can’t
adjust using inner pattern you can select HDMI item, and
you can adjust.
- In manual Adjust case, if you press ADJ button of service
remocon, and enter “Ez-Adjust Menu – 7. White Balance”,
then  automatically  inner  pattern  operates.  (In  case  of
“Inner” originally “Test-Pattern. On” will be selected in The
“Test-Pattern. On/Off”. 
O
Connect all cables and equipments like Pic.5)
O
Set  Baud  Rate  of  RS-232C  to  115200.  It  may  set
115200 orignally.
O
Connect RS-232C cable to set
O

G
” button
of navigation key. (When press “
G
” button then set will
go to full white mode)
- Adjust at three mode (Cool, Medium, Warm)
- If “cool” mode 
Let  B-Gain  to  192  and  R,  G,  B-Cut  to  64  and  then
control R, G gain adjustment High Light adjustment.
- If “Medium” and “Warm” mode Let R-Gain to 192 and
R,  G,  B-Cut  to  64  and  then  control  G,  B  gain
adjustment High Light adjustment.
- All of the three mode 
Let  R-Gain  to  192  and  R,  G,  B-Cut  to  64  and  then
control G, B gain adjustment High Light adjustment.
- With volume button (+/-) you can adjust.
- After all adjustment finished, with Enter (_ key) turn to
Ez-Adjust  mode.  Then  with  ADJ  button,  exit  from
adjustment mode
