5.3. Foot switch

When the foot switch is 

pressed the system starts 

the process of coagulat-

ing the defined spot pat

-

tern with the 532 nm laser 

beam. The laser emission 

can always be interrupt-

ed by releasing the foot 

switch if the patient´s eye 

has moved or there is any doubt about the function of the 

system. The system terminates the drawing of the pattern 

instantly when the foot switch is released.

If the foot switch stays pressed after the pattern is drawn, 

the system does not continue the coagulation. To produce 

a new laser figure, the foot switch must be released and 

repressed.

The foot switch is solidly connected to the laser console 

box.

Connecting the foot switch:
