3-2-2 Confirmation
• We confirm whether "0xBF(480i)/0xC8(1080i)" address of
EEPROM "0xA2" is "0xAA" or not.
• If "0xBF(480i)/0xC8(1080i)" address of EEPROM "0xA2"
isn't "0xAA", we adjust once more
• We can confirm the ADC values from "0xB9~0xBE(480i)/
0xC2~(1080i)" addresses in a page "0xA2"
*Manual ADC Confirmation using Service Remocon. After
enter Service Mode by pushing "INSTART" key,
