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 disc to
move the raster.
CAUTION
It is necessary to look
into the lenses to per-
form these adjust-
ments. To avoid eye
discomfort while look-
ing into the lenses,
reduce the contrast
and gradually in-
crease the brightness
level until the raster
becomes visible on
the face of the CRT.
Warning : In order to ensure maximum CRT longevity and to avoid CRT
damage, do not shift the raster outside the phosphor area of the CRT.
To start the adjustment, use the arrow keys to highlight Raster shift and press
ENTER to display the coarse shift menu. Select 'Green horizontal' and adjust for
correct raster position in horizontal direction on the phosphor.
Continue with 'Green vertical', then with 'Red vertical' and with 'Blue vertical' until
the rasters of the 3 tubes correctly centered on the phosphor.
Select with ê or é
then <ENTER>
<EXIT> to return.
