CRT projection angle adjustment
The projection angle of the red and blue CRT's is dependent on the
desired size of the projected image. If the centers of green, blue and
red do not coincide, the CRT projection angle must be adjusted. Never
try to correct this misalignment with the shift correction or the static
convergence controls. These controls may only be applied to correct
small errors which cannot be corrected by the CRT angle adjustment.
Ensure that the rasters are centered on the CRT face.
Press ENTER to start the CRT angle adjustment procedure. A
crosshairs (green and red) will be displayed on the screen.
The same projection angle is mis-aligned for new
screen width SW2. Re-alignment is necessary.
Each screen width change requires readjust-
ment of the projection angle.
