Raster Shift Adjustment
The green raster must be centered both horizontally and vertically on
the center of the CRT surface. To center the green raster, look into
the green lens and use the control disk to move the raster.
CAUTION
It is necessary to look into the lenses to perform these adjustments.
To avoid eye discomfort while looking into the lenses, reduce the
contrast and gradually increase the brightness level until the raster
becomes visible on the face of the CRT.
