Note: If the Venturi pump option is On, you cannot access the Fusion™ Fluidics
screen. There is no Occlusion Mode or CASE Mode with Venturi.
3. Use the Up and Down arrows at the bottom of the screen to adjust the:
• CASE Vacuum (CASE) – This is the optimum occlusion vacuum setting
• Upper Threshold (Up) – This is the maximum threshold vacuum setting,
which is maintained for the amount of time defined by the Up Time
Threshold.
• Lower Threshold (Down) – After the occlusion is cleared, the vacuum is
reduced to the lower vacuum threshold setting to allow the occlusion to be
safely cleared, and then gradually returned to the previous levels.
4. Use the Right and Left arrows in the graphic to change the Up Time
Threshold. The Up Time Threshold is the maximum time that the maximum
threshold vacuum is maintained.
