Next, move HOD along X-axis (Do not move in Y-axis) until the other offset boss can be seen.

Loosen screws (a) & (b) and move ATC with ATC support angle until the boss is nearly centered in

the CRT.

Repeat this procedure with the 2 bosses until Y-axis displacement is to within 0.1mm at both ends

and then tighten screws (a) & (b).

Since camera aperture is 6.3mm and boss diameter is 2.5mm, a visual judgement must be made.

(9) Reenter MS parameters of ATC offset.
