1) LCD EEP &DIG EEP

- LCD board and digital board can simultaneously backup the data of gamma (uniformity) and
flicker adjustment, because they have the same capacity of EEPROM.

- LCD EEP: It indicates the status of EEPROM in the LCD board.
* Cremo: With the eguipment used during engine assembly at the factory, it indicates that the adjusted

gamma and flicker data is stored.

* Download: It indicates that the gamma and flicker data on the digital board is downloaded and

stored through D->L Trans(14) operation.
