3-1. BEAM LANDING

Preparation:

•Feed in the white pattern signal.

•Before starting, degauss the entire screen.

1.Input a raster signal with the pattern generator.

2.Loosen the deflection yoke mounting screw, and set the purity control to the center as shown in Fig.2.

3.Turn the raster signal of the pattern generator to green.

4.Move the deflection yoke backward, and adjust with the purity control so that green is in the center and red and blue are at the sides evenly. (Fig.3)

5.Move the deflection yoke forward, and adjust so that the entire screen becomes green. (Fig.1)

6.Switch over the raster signal to red and blue and confirm the condition.

7.When the position of the deflection yoke is determined, tighten it with the deflection yoke mounting screw.

8.When landing at the corner is not right, adjust by using the disk magnets. (Fig.4)
