    SET-UP FOR ADJUSTMENT 1. CRT ADJUSTMENT Because the video signal output from a pattern generator is used as 1-1. Precautions the adjustment signal input during adjustment, the video signal (1) Receive the white raster signal, and then perform aging for at output from the pattern generator must conform with the least 20 minutes.
  • Page 32 (4) The composition of each magnet is as shown in Fig. 1-4. In making adjustments, rotate the lock ring clockwise (looking from the CRT’s back screen) and disengage. Be careful not to loose the lock ring too much. If the magnet assembly has become shifted during adjustments, secure it to the position in Fig.
  • Page 33 As there is occurrence of convergence distortion after In Fig. 1-7, two 4-pole magnets are stacked together so as to be of completing the landing adjustments, be sure to carry out the same polarity. Move the B and R beams to their respective convergence adjustments.
