2-6. 2-POLE MAGNET AND CENTERING MAGNET ADJUSTMENT
1. Set the picture mode to PRO and picture to MAX. 2. Either select the PJED Test Pattern dot hatch signal or apply an external dot signal. 3. Cover the red and blue CRT lenses with lens caps to allow only green to show (or use the method shown in the note below for turning off the CRTs individually without using lens caps). 4. Turn the focus VR on the focus block to the left (counter clockwise) and set it to overfocus to enlarge the spot. 5. Adjust the CRT�s 2-pole magnet so that the small bright spot is in the center. 6. Align the focus VR on the focus block and set it for the best focus. 7. Apply a Monoscope signal to the set. 8. Adjust the H-CENTERING and V-CENTERING roughly by the centering magnets. 9. Check 2-pole magnet adjustment. If necessary repeat steps 1-6. 10. Repeat steps 1 through 9 for the red CRT covering the green and blue CRT lenses with lens caps to allow only red to show (or use the method shown in the note below for turning off the CRTs individually without using lens caps) and adjust the red focus control on the focus block. 11. Repeat steps 1 through 9 for the blue CRT covering the red and green CRT lenses with lens caps to allow only blue to show (or use the method shown in the note below for turning off the CRTs individually without using lens caps) and adjust the blue focus control on the focus block.
2-8. 4-POLE MAGNET ADJUSTMENT
1. Set the picture mode to PRO and picture to MAX. 2. Receive the Dot signal. 3. Cover the red and blue CRT lenses with lens caps to allow only green to show (or use the method shown in the note below for turning off the CRTs individually without using lens caps). 4. Turn the (green) focus VR on the focus block to the right (clockwise) and set it to under-focus to reduce the spot. 5. Adjust the 4-pole magnet so that the small spot in the center of the screen becomes round for green and red. 6. Adjust the blue spot to an oval shape X:Y=1:1.2 Note: If lens caps are unavailable, you can cut off the unnecessary color beams by controlling the service mode 2150P-2 1 RGBS.
Use the center dot
x y x : y = 1:1 (Green, Red)
2-9. BLUE DEFOCUS ADJUSTMENT
1. Setup: Apply a Dot Hatch Signal and set the mode to Pro Mode. Change the color temperature to Cool in the user�s menu. 2. Cover the red and green CRT lenses with lens caps to allow only blue to show (or use the method shown in the note below for turning off the CRTs individually without using lens caps). 4. Turn the blue focus VR on the focus block to the right (clockwise) to make the round dot oval.
Note: If lens caps are unavailable, you can cut off the unnecessary color beams by controlling the service mode 2150P-2 1 RGBS.

2-7. CENTERING MAGNET ADJUSTMENT
Not required - Combined with 2-6 2-Pole And Centering Magnet Adjustment.
D1 Blue D1:D2 = 1:1.2
5. Check the flare with a high luminance signal to make sure the flare is minimal while the bright spot is located in the center, If not, readjust the 2 and 4-pole magnets. 6. Check for uniformity on a 100% IRE to an all white signal. Note: If lens caps are unavailable, you can cut off the unnecessary color beams by controlling the service mode 2150P-2 1 RGBS.
