Notes: (1) When adjusting the R, turn off the B using any one of the following procedures as required.
(a) Short-circuit the 2P subminiature connector plug pins on the B CPT l?W.B.
(b) Apply cover to the B lens.
(2) When adjusting the B, run off the R using any one of the following procedures as requuired.
(a) Short-circuit the 2P subminiature connector plug pins on the R CPT P.W.B.
(b) Apply cover to the R lens.
(3) The position of VRs and the movement of the bright lines are shown in Fig. 2-17-l and Fig, 2-17-2.
