Random Access Adjustment Mode
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.
ENTER will select green raster shift adjustment
EXIT returns to random access adjustment mode menu.
