ADJUSTMENTS
5 Rough adjustments
(1) Black level adjustment Signal:White 10%
Adjust R LOW, G LOW, and B LOW to the point where the CRT starts lighting up.
(2) HI LIGHT adjustment Signal:White 50%
Adjust R HI, G HI, and B HI so that the CRT becomes white. First, adjust so that the brightness of R, G, and B
becomes the same, and while maintaining that brightness, balance R, G, and B, and adjust so that the CRT
becomes white.
(3) LOW LIGHT adjustment Signal:White 20%
Adjust R LOW, G LOW, and B LOW so that the CRT becomes gray.
(4) Convergence adjustment Signal:White 50%, 20%
Repeat (2) to (3) and converge the light. If the HI LIGHT of
R, G, and B is moved, their LOW LIGHT will change greatly. Therefore, pay special attention to the value of the
LOW LIGHT.

6 LINEAR WHITE adjustment
When white peak signals such as WINDOW are input, due to the characteristics of the Blue CRT, there is a
tendency for the peak to become yellow compared to other colors. The linear white adjustment is performed to
correct this tendency.
Blue becomes weak when data is set to UP and strong when set to DOWN. If Linear White is added excessively,
the ABL voltage becomes unbalanced and the medium luminance of blue may be erased, etc.
Also make sure that the blue is not blur when MULTI ON is set because the top left and bottom left of the screen are affected
first.
