•Regarding the laser activation duration, the foot switch has absolute priority over the set
pulse times for safety reasons, i. e. when the foot switch is not pressed any longer, the
emission of laser light is stopped immediately even if the preset pulse time has not ended
yet.
•To prevent unintentional changes of the laser parameters during the surgical procedure, all
keys are out of function while the foot switch is pressed. Scan shapes can be rotated only
in scanner mode.
•The laser power is monitored just before emission of laser light.
•Pressing the EMERGENCY-STOP switch will deactivate the emission of laser light
immediately in case of emergencies.
