mode. (EEPROM is initialized when AC Power is ON first.)
 If the change of FOS data is needed after M.P, it is possible by writing Mode Data with
EEPROM write command or modifying the Mode Data in MICOM itself.
# Caution) Must keep power-on more than 3 seconds after AC Power-on first time.
3.2.4 Color coordinates adjustment and Luminance adjustment.
3.2.4.1 Color coordinates adjustment
■ Monitor Contrast / Brightness
- Contrast : 70
- Brightness : 100(Max)
- Energy saving : low
■ CA-110: channel: 8 / CA-210: channel
14
■ Signal Generator : At cut-off and drive  16 step pattern for ADC
- Output Voltage : 700 mVp-p
- Output Mode : Mode 12( 1920x1080+ 60Hz )mode Setting.
3.2.4.2.Adjustment : Board Assembly Line
MP58 model use internal ADC, no need connect D-SUB cable
Internal ADC steps as below
On AC power on with Aging mode, checking the ADC values and then decide to do or not,
If don’t use internal ADC, please follow below step
 Input 16 step pattern for ADC (Mode12, pattern 11). (Video level : 700 mVp-p)
 Adjust by commanding AUTO_COLOR_ADJUST
 Confirm “Success” message in Screen or Check the data of 0x0D, 0x0E address of
EEPROM(0xA8) is 0xAA after waiting 5 seconds
 If there is “FAULT” message or the data of 0x0D, 0x0E address of EEPROM(0xA8) is not
0xAA, do adjust again
 If all Adjustment is completed, the values of 6500K, User Color and 9300K are saved
automatically.
3.2.4.3. Confirm at Total Assembly Line: adjustment
• Read ADC OFFSET and GAIN flags from 0xA8 0x0D, 0x0E on NVRAM
• If those values are not 0xAA on Aging mode, must do internal ADC calibration.
• If the result of internal ADC calibration is OK, save the ADC result and make the OFFSET
and GAIN flags to 0xAA and make the Internal_ADC flag to INTERNAL.
• Display the result of ADC on Aging Mode OSD and Service OSD
