Function versus Mode
Enables footpedal proportional aspiration rate via peristaltic pump, permitting required vacuum for effective aspiration.
Actual vacuum and requested aspiration rates displayed whenever footpedal treadle ≥ Postion 2 with maximum
aspiration rate at Postion 4.
Peristaltic pump actuation is only enabled when selected maximum vacuum has not been exceeded.
Any vacuum generated by the peristaltic pump is automatically and safely vented whenever
footpedal treadle position is returned ≤ Position 2.
Enables footpedal proportianal U/S Power to be delivered to the attached
ultrasonic handpiece with maximum U/S Power at Position 4.
Requested U/S Power is displayed whenever footpedal treadle position ≥ Position 3.
Aspiration rate is fixed at the selected aspiration rate.
Same as U/S except U/S Power is pulsed at
10 pulses / sec.
The vitrector is actuated at selected cut rate whenever
footpedal treadle position is ≥ Position 2.
Actuates reverse peristaltic pump rotation ( 20cc / MIN )
Electrically heat targeted tissue held by the cautery forceps at the set cautery power
As above except maximum selected U/S Power is delivered to the attached U/S handpiece
in 20 ( LO ), 40 ( MED ), 90 ( HI ) or 200 ( XTR ) mSEC selected constant-width pulses.
Minimum pulse repetition rate is 1 PPS (Position 3 ) and increases with footpedal treadle depression to
maximum pulse repetition rate ( Position 4 )
