Alignment Procedure
1. Alignment procedure (for function adjustment)
A. Preparation:
1. Setup input timing ICL-605( 1280x1024@75Hz ), 32-Grays pattern.
2. Setup unit and keep it warm up at least 30 minutes.
B. Timing adjustment:
1. Enter factory setting area (press “ENTER”, “EXIT” and then press “SOFTPOWER”).
2. Check the settings to following values:
Contrast = 50
Brightness = 90
OSD time = 20
Color = Normal
Language = English
Then, turn off the monitor power.
3. Turn on power enter user area.
C. Color balance adjustment:
1. Enter factory setting area (press “ENTER”, “I-Key” and then press “SOFTPOWER”).
2. Setup input timing ICL-605(1280x1024@75Hz), 32-Gray pattern (pattern 48) .
3. Press “I-KEY”, and than OSD will show “White Balance” item and than press “ENTER” button
to do auto color.

Alignment Procedure
D. Color adjustment:
1. Setup input timing ICL-605, white pattern .
2. Confirm auto color adjustment had already done.
3. Measure color temperature by Minolta CA-110 (or equivalent equipment).
4. Check the color temperature Bluish, Reddish & Normal. The color temperature specification
as follows:
White Balance

6. Checking if the picture is no good, reject this monitor.
7. To check the power consumption by disabling “burn-in mode” setting
8. To clear user data and program complete DDC data to monitor by IIC bus communication.
E. Writing EDID file:
1. Setup a PC with DDC card.
2. Connect PC to monitor with a D-sub signal cable.
3. Please refer to the C212 for the correct EDID file.
4. Runs the writing program to write the EDID file into EEPROM .
5. Read EEPROM data and confirm it to match with the C212 document definition.
F. Command definition :
PC Host will send 0x7C IIC slave address and then following 4 bytes command
