Vision System
Probe cutting at a preset rate is activated when the applicable footswitch switch
is momentarily activated. The default activation switch is the right horizontal switch
but may be configured differently for each doctor. To view the current configuration,
press the footswitch icon in the upper left corner of the display.
The controls for each panel in Momentary submode are the same as in 3D submode
with the following exceptions:
No Vacuum Start Up/Down buttons - Vacuum always begins at zero.
No Flow Start Up/Down buttons - Flow always begins at zero.
No Cut Rate Start Up/Down buttons - Cut rate is a constant rate set by the End
buttons and activated by the programmed switch on the footswitch.
Vitrectomy: PROPVAC SUBMODE
The Proportional Vacuum (PropVac) submode contains values for maximum vacuum
limit and cut-rate set point. As the footpedal is depressed the vacuum increases
linearly up to the End limit with the actual vacuum displayed in the Actual Value box
and its linear equivalent reflected in the progress bar. The End value can be adjusted
using the Up/Down arrow buttons or selecting the Configuration button to display the
Configuration popup that has a slidebar for large numeric adjustments in vacuum.
