Note : Make these 2 adjustments (3-S1, 3-S2) after perfoming section 3-13. 3-S1. W/B plunge correction adjustment S1-1. Adjustment of NTSC composite 1) Input the 525 all white (with burst) cut-off signal. 2) Adjust the brightness to a value below 10 cd/m2 with CONT and BRT VR. Brightness adjustment:3 cd/m2 3) Turn CHROMA VR to MIN, and measure the color temperature. 4) Turn CHROMA VR to MAX, and make adjustment with
NTSC B-Y
S1-4. Adjustment of DIGITAL 1) Input the DI 525 all white cut-off signal. 2) Repeat the operations S1-1. 2) and 3). 3) Turn CHROMA VR to MAX, and make adjustment with DIGITAL R-Y and DIGITAL B-Y so that the color temperature will be the same as the value measured in item 2). Standard adjustment: The difference should be within 2 JND when CHROMA MIN n MAX. S1-5.
