than 0 , R gain can adjust more than 210 ) and
change the others ( G/B Gain ).
Adjust two modes (Medium / Warm), Fix the one of R/G/B gain
to 192 (default data) and decrease the others.

- PDP : Color Analyzer (CA-100, CA-100+, CA210) probe
should be firmly attached to the Module
- LCD : Color Analyzer (CA-210) probe should be within 10cm
and perpendicular of the module surface (80°~ 100°)
