Calibrating and Adjusting
To adjust focus, landing, and convergence
8Move the deflection yoke forward until the entire raster is green.
Landing adjustment is easier if the yoke is moved all the way forward and then moved back until the raster is completely green.
9Using the Color Purity key, replace the green raster with red and then blue raster, each time checking for proper landing adjustment (color purity of each).
10If the landing is not correct in step 9, repeat steps 6 through 9 for the best compromise.
Purity control corrects this area
Deflection yoke position corrects these areas
11If the landing is not correct in step 10, readjust purity magnets for best landing of each color.
12When the landing adjustment is complete, tighten the deflection yoke clamp screw just enough to keep the yoke from moving. DO NOT over tighten or you might damage the CRT.
