Purity and convergence procedure
Adjustment is necessary only if the CRT or the deflection yoke is replaced or if the setting was disturbed. The complete procedure consists of: 1. Vertical raster shift adjustment. (Only for models with purity/convergence assembly with 4 pairs of rings). 2. Initial static convergence. 3. Setting the purity. 4. Final static convergence.
Vertical raster shift adjustment
(only for models with purity/convergence assembly with 4 pairs of rings). Apply a green pattern with a horizontal line, adjust the deflection yoke so that has no tilt, then secure it. Adjust center line of the pattern with the mechanical center of the CRT, this center is determined by two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs are place at 3 o�clock to reduce its magnetic field effect (see Fig. 9 and Fig. 10) open the tabs the same angle from the center, until the center line of the pattern becomes a straight line, centered with the marks of the CRT. (see Fig. 11)
Center line from pattern
When the CRT or the yoke is replaced
Place the yoke on the CRT neck (do not tighten the clamp). Place the vertical raster shift tabs at 3 o�clock (90o from the purity and convergence tabs)

Turn the receiver ON. Operate the receiver for 60 minutes using the first purity check field (white screen) to stabilize the CRT. Fully degauss the receiver by using an external degaussing coil. Slide the deflection yoke back and forth on the neck of the CRT until it produces a near white, uniform raster.
