Vacuum for fluid extraction is provided to the syringe proportional to footpedal
depression. Max Limit vacuum is reached at full depression. The controls on the
Extraction panel have the following functions:
Vacuum End Up/Down Buttons - Sets the vacuum level at full treadle. Start value
is always zero.
Vacuum Progress Bar and Numerical Value - Displays the current vacuum level.
Extraction Configuration Button - Displays the configuration that simplifies large
value changes by providing slider controls.
Viscous Fluid Control (VFC) Mode: Inject Submode
In this submode injection pressure to the syringe is provided proportional to the
footpedal position up to the Max Limit setting. Vacuum is available in Bimanual mode
by pressing the Bimanual On/Off button.
WARNINGS!
• Double check the cannula connected to the syringe for a tight connection. It must
not be allowed to come loose.
• Adjust the Max Limit air pressure in accordance with the viscosity of fluids to be
injected.
Vacuum Panel controls:
Bimanual-Vacuum On/Off Button - Turns vacuum on or off. When Bimanual
mode is on, the control displayed is a dual value control.
Vacuum End Up/Down Buttons - Sets the vacuum level at full treadle. The Start
value is always zero.
Vacuum Progress Bar and Numerical Value - Displays the current vacuum level.
