comes to the center of the effective screen (so that A and
A’ are almost equal). (Fig. 1-6) When this adjustment is
complete, take note of the H. CENTER adjustment data.
7. Adjust the H. PHASE data so that the signal area
comes to the center of the raster area (so that B and B’
are almost equal). (Fig. 1-6) When this adjustment is
complete, take note of the H. PHASE data.
8. Adjust the H. BLK. LEFT data so that the left-most
end of the raster area is positioned at 2.0 mm outside
the left-most end of the crosshatch signal area. (Fig. 1-
7.) When this adjustment is complete, take note of the
H. BLK. LEFT adjustment data.
9. Adjust the H. BLK. RIGHT data so that the right-most
end of the raster area is positioned at 2.0 mm outside the
