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 con-
vergence to open or close the V. STAT magnet.
When the V.STAT magnet is moved in the
direction of arrow
and
, Red, Green and
Blue dots move as shown below.
G
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
