5.4.2 PHACO (U/S) NORMAL MODE (CONTINUED)
Fixed: Phaco energy is controlled in a “FIXED” fashion by the Foot Pedal. When the foot pedal
reaches position (3), the U/S Power delivered is the preset value noted to the left of the arrow
keys and on the U/S Power (%) display.
Releasing the foot pedal to position (2) or (1) will stop the Phaco power and continue the
operation of the current foot pedal position, either Irrigation/Aspiration or Irrigation only,
respectively. Releasing the foot pedal completely will cease all operations: Phaco, Aspiration, and
Irrigation.
Pulse: When the foot pedal is in position (3), the Pulse function will deliver U/S Phaco power from
zero pulses (Continuous US Power) to the maximum of ten (10) US Power pulses per second.
Pulse also works with Fixed or Linear U/S Phaco power delivery.
