Geometry Adjustments

The geometry adjustments have to be done only on the green image. These adjustments are
automatically implemented for the other color images : Left-right (EW) and Top-Bottom Cor-
rections, Blanking, Horizontal Amplitude, Vertical Amplitude, Vertical Linearity and Horizon-
tal 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
- Horizontal Size
- Vertical Linearity
- Vertical Size
- Blanking

The convergence corrections are disabled during geometry corrections. The blanking correc-
tions 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 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.

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 visual indication
of the horizontal phase adjustment.

ENTER will display Geometry menu.
EXIT will return to Internal Crosshatch Selection or Setup
Pattern Selection Menu.
ADJUST returns to operational mode.
