Raster centering

The raster must be centered on the CRT screen surface of each tube, therefore, it

is necessary to look into the lenses.

Caution : To avoid eye discomfort while performing these adjustments, reduce the

contrast and gradually increase the brightness level until the raster becomes

visible behind the image.

Warning : In order to ensure maximum CRT longevity and to

avoid CRT damage, do not shift the raster outside the phos-

phor area of the CRT.

Press ENTER to display the raster on

the green CRT.

Look into the green lens and shift the

raster with the control disc until it is
