Clearing a Clogged Probe
WARNING: The pressure differential created in the canister during the procedure can cause blood
discharge.
NOTE: If tissue, blood, or any other fluid clogs or fills the probe during the procedure, attempt to
clear the probe by pressing and immediately releasing the VAC button on the active input
device (holster, remote footswitch, or remote keypad) to initiate cutter movement and a
vacuum pulse.
NOTE: The specimen management system needs to be attached to the probe for this function to
be performed properly.
NOTE: Press and hold the VAC button to activate on-demand VACUUM for the duration of the
button press (up to 15 seconds). Quickly pressing and releasing the VAC button
commands the system to clear the probe.
