4-3. Confirmation
(1) We confirm whether “0xBF(480i)/0xC8(1080i)” address of
EEPROM “0xA2” is “0xAA” or not.
(2) If “0xBF(480i)/0xC8(1080i)” address of EEPROM “0xA2”
isn’t “0xAA”, we adjust once more
(3) We can confirm the ADC values from “0xB9 ~ 0xBE(480i) /
0xC2 ~ (1080i)” addresses in a page “0xA2”
(4) Manual ADC Confirmation using Service Remocon. After
enter Service Mode by pushing “INSTART” key,
