Allow a 30 minute warm-up period prior to making the following adjustments:
3-1. Landing Rough Adjustment
1. Enter the full white signal.
2. Adjust the contrast to the maximum.
3. Input full green signal.
(Note: Turn off the outputs from R ch and B ch of SG)
4. Move the DY backward and adjust the purity magnet
coarsely so that 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 DY Tilt, use TLV of DY for this adjustment. Fix
the Register "TILT" to 0.
7. Lightly tighten the DY screw.
3-2. Landing Fine Adjustment
1. Place the set in the Helmholtz coil.
2. Set TLH plate to the zero position.
3. Adjust Purity Magnet on the Neck Assembly to zero
position and secure it with white pin.
4. Set "VPIN SAW TOP" and "VPIN SAW BTM" to zero
position.
5. Display a plain green pattern.
6. Degauss CRT and shield with hand-degausser.
7. Perform auto-degauss.
8. Attach a wobbling coil to the specified position of CRT.
9. Attach a landing adjuster sensor on the CRT.
10. Using a landing checker, adjust the DY position, purity,
tilt of DY.
11. Tighten the DY screw.
Clamping torque: 22 ± 2 kg.cm (2.2 ± 0.2 N.m)
12. Perform auto-degauss.
13. Adjust top and bottom pin pitching DY by up and down
with two wedges so that (a) is equal to (b)(see the figure
at right). Also, leave the yaw of DY to the physical
center position with another two wedges.
Fasten wedges so that DY does not move.

four-pole magnet.
3. Roughly adjust HMC and VMC with a six-pole magnet.
3-4. Convergence Fine Adjustment
1. Display crosshatch pattern with R and B.
2. Adjust H. STAT and V. STAT with 4-pole magnet.
