ADJUSTMENT INSTRUCTIONS O You can check whether circuit adjustment is operated well or not, as below. (1) Display RGB1 to the Main picture, CVBS to the Sub picture in the TWIN PICTURE. (2) To check the MIN-Bias, input Full Black (0 gray) signal into CVBS and RGB1 input port at the same time from the Pattern Generator. (3) To check the MAX-Bias, input Full White (255 gray) signal into CVBS and RGB1 input port at the same time from the Pattern Generator. (4) Compare Black Level with White Level by eye.
ADJUSTMENT INSTRUCTIONS 2) After turning the RV401, voltage of D.M.M adjustment as 6-3. White Balance Adjustment same as Vs voltage which on the label of the PCB Right/Top. O Operate the Zero-calibration of the CA-100, then stick sensor (Deviation : ±0.5V) to PDP module surface when you make adjustment. O For manual adjustment, it is also possible by the following P805 Va sequence.
