(1) Remote Controller for Adjustment
(2) Color Analyzer (CS-1000, CA-100,100+,CA-210 or same
product ): CH 10 (PDP)
* Please adjust CA-210, CA-100+ by CS-1000 before
measuring
(3) Auto W/B adjustment instrument(only for Auto adjustment)
(4) 15 Pin D-Sub Jack(RGB) is connected to the AUTO W/B
EQUIPMENT.
9-2. AUTO White Balance Process.
Before Adjust of White Balance, Please press POWER ONLY
key
Adjust Process will start by execute I2C Command (Inner
pattern (0xF3, 0xFF)).
O Color temperature standards according to CSM and Module
O CS-1000/CA-100+/CA-210(CH 10) White balance
adjustment coordinates and color temperature.
9-3. Manual W/B Process (using adjusts Remote control)
Please Adjust in AV 1 MODE
(1) Enter “PICTURE RESET” on Picture Mode, then turn off
