Horizontal and Vertical Static Convergence
1. (Moving vertically), adjust the V.STAT magnet so that the red,
green and blue dots in the center of the screen are separated
from each other.
2. Adjust the BMC (Hexapole) magnet so that the red, green and
blue dots are aligned in a straight line.
3. Adjust the BMC (Hexapole) magnet so that the red, green and
blue dots are balanced (ie. equal distance) on either side of the
green dot.
4. (Moving horizontally), adjust the H.STAT VR magnet so that
the red, green and blue dots converge on top of each other in
the center of the screen.
•
The respective dot positions resulting from moving each magnet
interact, so be sure to perform adjustment while tracking.
Use the V. STAT magnet to adjust the red, green and blue dots
so they coincide at the center of screen (by moving the dots in
the horizontal direction).
