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 stick 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.
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 control disk to highlight Raster shift
and press ENTER to display the green raster on the phosphor.
Press EXIT to return to the Geometry menu.
Note : Horizontal and Vertical shifts for Red and Blue should
end up with a setting close to 50%. If these settings are
significantly greater or lesser than 50%, contact a BARCO
authorized service technician.
