    Set DY four-pole magnet to mechanical center
     before adjustment.
    This should be prime mode.

1.     Receive R.B. cross-hatch.
2      Adjust H.STAT and V.STAT at four-pole magnet.

1.   Enter the full white signal.
2.   Adjust the contrast to the maximum.
3.   Input full green signal.
4.   Moving the DY backward, and adjust coarsely the purity

magnet sothat a green raster positions in the center of
screen.

5.   Moving the DY forward, adjust so that an entire screen
      becomes pure green.
6.   Adjust the tilt of DY, and tighten lightly with a clamp.

1.   Place the set in the Helmholtz coil.
2.   Enter a green signal only.
3.   Degauss the entire screen with hand-degausser.  Then auto-
      degauss it.
4.   Attach a wobbling coil to the specified position of CRT
      neck.
5.   Attach a landing adjuster sensor on the CRT.
6.   Using a landing checker, adjust the DY position, purity,
      tilt  of DY.
7.   Clamp the DY screw.
                Clamping torque: 22 + 2 kgcm (2.2+ 0.2 N.m)

1.  All digital convergence data should be zero by MCP.
2.   Enter the white crosshatch signal.
3.   Adjust roughly the horizontal and vertical
      convergence at four-pole magnet.
4.   Adjust roughly HMC and VMC at six-pole
      magnet.

*The parts above (     ~     ) are necessary for DAS adjustment.
