Inside PATTERN is used when W/B is controlled. Connect to 
auto controller or push Adjustment R/C POWER-ON -> Enter 
the mode of White-Balance, the pattern will come out.
 Auto-control interface and directions
(1)  Adjust  in  the  place  where  the  influx  of  light  like  floodlight 
around is blocked. (Illumination is less than 10ux).
(2)  Adhere closely  the Color Analyzer ( CA210 ) to the module 
less  than  10cm  distance,  keep  it  with  the  surface  of  the 
Module and Color Analyzer’s Prove vertically.(80~100°).
(3) Aging time
-  After  aging  start,  keep  the  power  on  (no  suspension  of 
power supply) and heat-run over 5 minutes.
-  Using ‘no signal’ or ‘full white pattern’ or the others, check 
the back light on.
