1.Loosen the Ring Lock and align red with blue dots or Crosshatch at the center of the screen by rotat- ing (RB) C.P. Magnets. (See Fig. 7)

2.Align red / blue with green dots at the center of the screen by rotating (RB-G) C.P. Magnet. (See Fig. 8)

3.Paintlock the C.P. Magnets after adjustment.

4.Remove the DY Wedges and slightly tilt the De- flection Yoke horizontally and vertically to obtain the best overall convergence.

5.Fix the Deflection Yoke by carefully inserting the DY Wedges between CRT and Deflection Yoke.
