WARNING

SHOCK HAZARD. Potentially dangerous voltages are present on the pins of R302 and R306. Use an insulated screwdriver for adjustment.

16. Turn R302 counterclockwise just until the raster disappears. Turn R302 counterclockwise approximately 1/16 turn more.

17. Turn R402 clockwise until the normal display intensity is visible.

NOTE:

Raster will not reach normal intensity if R302 is turned too far counterclockwise.

18. Adjust R111 for an overall pattern width of 106 ±2mm. Adjust RI 13, Horizontal Linearity (FRAME UN) so that each box is approximately the same width.

NOTE:

The adjustments of R111 and R113 are interactive. Repeat the above step until both measurements are correct.

19. Adjust R402 to obtain a dim display. Adjust R306, Focus, for maximum sharpness of the display characters.

20. Adjust the yoke rings to center the test pattern on the CRT within 2mm. Confirm that the difference in height from the right side to the left side of the test pattern is less than or equal to 1mm. Check that the difference in width from the top to the bottom is less than or equal to 2mm.

21. Turn R402 clockwise until the normal display intensity is visible.
