1-1) Confirmation
· We confirm whether "0xAA (RGB)" address of EEPROM
"0xA2" is "0xAA" or not.
· If "0xAA (RGB)" address of EEPROM "0xA2" isn't "0xAA", we
adjust once more
· We can confirm the ADC values from "0xA4~0XA9 (RGB)"
addresses in a page "0xA2"
*Manual ADC process using Service Remocon. After enter
Service Mode by pushing "ADJ" key, execute "4.ADC Adjust" by
pushing " " key at "ADC CALIBRATION: RGB".
