FOOTSWITCH 112101 USED IN SINGLE LINEAR MODE (SING. LIN.)
In the "IVP" mode (refer to section 8.7) the footswitch button located above and to
the left raises the I.V. pole and the button located below and to the left lowers the
I.V. pole. In the “IVP” mode it is possible to switch between Memories 1, 2, and 3
in the U/S mode and between Memories 1 and 2 in the I/A modes by rotating the
footswitch to the right.

FOOTSWITCH 112102 SINGLE LINEAR
When the main pedal is slightly pressed, the IRRIGATION valve opens, permitting
the fluid to enter the infusion circuit.
Pressing the main pedal beyond stop 1 starts the pump, which activates aspiration
and irrigation simultaneously. If the VACUUM linear control mode is selected on the
control panel, a further press on the footswitch will increase the aspiration level in
a linear manner.
In the vitrectomy mode when the surgeon presses the main pedal beyond stop 1,
this also activates the vitrectomy scalpel. If the linear mode is selected for the
CUTTING SPEED, a further press on the footswitch will increase the cutting speed.
In the U/S mode when the main pedal is pressed beyond stop 2, the
phacoemulsifier handpiece is activated. A further press on the footswitch will
increase the phacoemulsifier tip travel (U/S power) (if the linear control mode is
active) or the Burst Emission frequency.
In the U/S mode, if both aspiration and phacoemulsifier have been set in the linear
mode, the power level of aspiration and ultrasound will gradually increase as the
footswitch is pressed, until it is completely pressed down.
When the surgeon presses the switch located to the left of the pedal, an immediate
REFLUX will occur through the aspiration line of the connected handpiece. REFLUX
is a reverse flow caused by opening the specific valve that allows fresh balanced
