NOTE:
For the correct functioning of the unit select the pedal control mode that is compatible with the
pedal that is effectively attached to the control panel.

FOOTSWITCH 112101 USED IN DOUBLE LINEAR MODE (“DBLE. LIN.”)
As can be seen in the figure, the pedal unit consists of a main pedal that can be
moved vertically and/or horizontally and three separate buttons that activate
CONTINUOUS IRRIGATION,
switching between MMP
1-2 and MMP 1-2-3
(depending on the active
function), and the
Function Change.
When the main pedal is
slightly depressed, the
"IRRIGATION" valve opens,
permitting saline solution
to enter the infusion
handpiece.
When the main pedal is
pressed beyond the first
mechanical detent (MECH.
DETENT 1), the pump is
activated, thus allowing
irrigation and aspiration
to be active
simultaneously. Pressing
on the pedal again will
linearly increase the
degree of negative
pressure if the LINEAR control mode was selected for the negative pressure.
When the main pedal is rotated to the user's right, the vitreous cutter (or the
phacoemulsifier handpiece) is activated. If the linear control mode was selected, a
further rotation of the main pedal to the right will increase the cutting speed (or
the amplitude of oscillation of the phacoemulsifier tip).
When the main pedal is rotated to the user's left, REFLUX through the aspiration
line will occur immediately. Reflux is a "reverse" flow caused by opening the
REFLUX valve which allows balanced saline solution to enter the aspiration line. A
low-frequency (800 Hz) warning sound will be generated by the instrument.
