Horizontal Phase Adjustment

Push the control disk up or down to highlight H PHASE on the Geo-
metry Menu and then 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 the >< 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
will give a visual indication of the horizontal phase adjustment.
