Geometry Adjustments
The geometry adjustments have to be done only on the green image. These adjust-
ments are automatically implemented for the other color images : Left-right (EW) and
Top-Bottom Corrections, Blanking, Horizontal Amplitude, Vertical Amplitude, Vertical
Linearity and Horizontal Phase.
Highlight GEOMETRY by pushing the control disc up or down and press ENTER to
display the geometry menu.
Within the Geometry Adjustment menu, the following adjustments are available :
- Horizontal Phase (not for internal # pattern).
- Raster Shift
- Left-Right Corrections
- Top-Bottom Corrections

The convergence corrections are disabled during geometry corrections. The blanking
corrections are only enabled during the blanking adjustments.
Horizontal Phase Adjustment
Push the control disc up or down to highlight H PHASE on Geometry menu and the
press ENTER.
Note : No horizontal phase adjustment is available on the internal # pattern.
For external sources :
If the raster shift is correctly adjusted, the H Phase text box is projected in the mid-
dle 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.
Note : If the genlocked pattern was selected, the external source will be displayed.
A bar scale and a number indicator (between 0 and 100) on the screen give a visu-
al indication of the horizontal phase adjustment.
