:
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.
What has to be done?
The raster of the separate colors must be centered both horizontally and vertically on the center of the CRT surface. To center the
raster, look into the lens of the respective color and use the cursor keys to move the raster.
