BLK) to the mechanical center.
@Input 16 steps monochrome green at 0.7Vp-p with
a timing signal of SVGA VESA(60).
@ Adjust R665(W SUB CONTRAST) and R6e6s(W
SUB BRIGHT) so that brightness of 16 steps is
best,....visual check.
@JInput gray pattern at 0.21Vp-p with a timing signal
of SVGA VESA(60).
® Adjust R870(R SUB BRIGHT) and R970(B SUB
BRIGHT) so that the chromaticity at the center of
the picture is x=0.280+0.005,y=0.3600.005
(middle-brightness white balance)
@Input gray pattern at 0.52Vp-p with a timing signal

SUB CONTRAST) so that the chromaticity at the
center of the picture is x=0.280+0.005,y=0.360+
0.005 (hi-brightness white balance)
@)Input gray pattern at 0.07Vp-p with a timing signal
of SVGA VESA(60).
@Adjust R851(R BLK) and R951(B BLK) so that the
chromaticity at the center of the picture is
x=0.280-£0.01,y=0.36020.01 (low-brightness
white balance)
(Repeat @ to © and adjust middle, hi and low-
brightness white balance.
note When majoring and adjustment using Minolta
CL-100.
