Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. 3. Observe the points a, b as shown in Fig. 4-1 through the microscope. Adjust the landing to the A rank requirements. 4. Orient the raster rotation to 0 eastward. 5. Tighten up the deflection coil screws. » Tightening torque: 108 ± 20 N (11 ± 2 kgf) 6. Make sure the CRT corners landing meet the A rank requirements. If not, stick the magnet sheet to correct it.
