GENERAL ADJUSTMENTS
SPECIFIC INFORMATIONS
(5) Adjust the sub-4-pole magnets only in case there is any deviation of Xv bow-shaped convergence. (To be usually set
at the initial position)
Align both sides with the sub-4-pole magnets and minimize the deviation of blue and red with the main 4-pole magnets.

correction piece into the clearance
of terminal board coils of the deflec-
tion yoke.
Note:
Perform insertion by turning the
metal side to the terminal board side
of the deflection yoke.
