Adjust H. STAT VR to coincide red, green and blue dots on the center of screen. (Horizontal movement) Adjust V. STAT magnet to coincide red, green and blue dots on the center of screen. (Vertical movement) If the red, green and blue dots do not coincide on the center of screen with H. STAT VR, perform horizontal convergence adjustment using H. STAT VR and V. STAT magnet as shown below. (In this case, H. STAT VR and V. STAT magnet effect each other.) Tilt the V.STAT magnet and adjust static convergence to open or close the V. STAT magnet.
If blue dot dose not coincide with red and green dots, perform following steps. Move BMC magnet (a) to correct insufficient H. static convergence. Rotate BMC magnet (b) to correct insufficient V. static convergence. In either case, repeat Beam Landing Adjtstment.
