How to adjust ?
If the raster shift is correctly adjusted, the H Phase text box is projected in the middle of the raster. At that moment, the "><" icon
indicates the middle of the raster.
Adjust the H Phase control until the middle of the projected image is equal with the middle of >< icon.
Image 1 : Push the cursor key to the right to correct.
Image 2 : Push the cursor key to the left to correct.
Note : If the genlocked pattern was selected during the start up of the random access mode, the external source will be displayed.
A bar scale and a number indicator (between 0 and 100) on the screen give a visual indication of the horizontal phase adjustment.

Raster Shift Adjustment
What has to be done ?
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 cursor keys 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.
Start up
To start the adjustment (image 1) :
1.
push the cursor key
é
or
ê
to highlight Raster Shift (menu 1).
2.
press ENTER to display the coarse shift menu (menu 2)
3.
Select first green horizontal and adjust.
4.
Continue with green vertical.
5.
Shift red and blue on green.
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.
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.
