The Triple Arc pattern is selectable in various orientations, depending on the spot
diameter, spacing, and curvature settings. You must select the spot diameter, spacing,
and curvature settings before selecting the pattern orientation. If you select the pattern
orientation and then select the spot diameter, spacing, and/or curvature settings, the
pattern returns to its default orientation.
To select the pattern orientation, drag your finger along the outside of the rotation guide
that displays in the pattern background.
Auto Advance Feature
If the Auto Advance feature is enabled, the first Triple Arc pattern is delivered when you
depress the footswitch, after which the system automatically rotates the pattern at 30
degree intervals. When you press the footswitch a second time, the pattern is delivered,
and the system automatically rotates pattern.
The orientation is selectable in clockwise and counter-clockwise on the Physician
Preferences.
