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.

NOTE : 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.

Note: The Horizontal Shift and Vertical Shift for Red and Blue should be set near 50%.

Be sure that the rasters are centered on the CRT faceplate.

Press the <ENTER> key to start the CRT angle adjustment procedure. Press the <ENTER> key to continue with the second part of the CRT projection angle adjustment.

Press the <ENTER> key to continue with the crosshairs alignment. Press the <EXIT> key to return to the previous menu.

Press the <ADJUST> key to return to Operational mode.

Loosen bolts A, B, C and D to pivot the red CRT until the center of the Red image and the center of the Green image coincide. When the angle of the red CRT is corrected, tighten the four bolts.

Press the <ENTER> key to continue with blue and green crosshairs. Press the <EXIT> key to return to the CRT projection angle adjust- ment menu.
