• Landing Rough Adjustment
1. Enter the full white signal.
2. Set the contrast to “CONT”=255.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so
2. Set the contrast to “CONT”=255.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so
that a green raster positions in the center of screen.
5. Moving the DY forward, adjust so that an entire screen be-
comes monogreen.
6. Adjust the tilt of DY, and fix lightly with a clamp.
Note: "TILT" shall be set at 0.
Note: "TILT" shall be set at 0.

aging for about 30 minutes, adjust so that it is exactly this
value.
value.
3. Demagnetize the CRT surface with the hand degausser , and
perform auto degaussing.
Note: Adjust in s non-magnetic field.
4. Attach the wobbling coil to the designated part of the CRT
4. Attach the wobbling coil to the designated part of the CRT
neck.
5. Attach the sensor of the landing adjustment unit on the CRT
surface.
6. Adjust the DY position and purity, and the DY tilt, and land-
ing of the center and 4 corners with the landing checker.
Purity
Adjust the green of corners 1 to 4, and center 6 to ±5 µm, and
red and blue to within ±7 µm of green, and the difference be-
tween red and blue to within ±10 µm.
Adjust the green of 5 and 7 to within ±10 µm, and red and blue
to within ±7 µm of green, and the difference between red and
blue to within ±10 µm.

Adjust the green of 5 and 7 to within ±10 µm, and red and blue
to within ±7 µm of green, and the difference between red and
blue to within ±10 µm.
(Set each corner to 1st frame of the crosshatch.)
7. For the up/down and left/right swing, swing the DY and in-
sert a wedge so that the up and down pins are equal at the top
and bottom and the horizontal trapezoid is equal at the left
and right. Insert the wedge firmly so that the DY does not
shake.
