Laser Emission Indicators
A laser emission icon appears on the control screen to alert you that laser
energy is being emitted. During the treatment beam delivery, the laser
emits an auditory signal correlating to the pedal used.
The system also verbalizes
"READY"
and
"STANDBY"
with a voice
indicator when the system is transitioned from mode to mode.
External Door Interlock
An external door interlock outlet and plug are provided to disable the laser
if the treatment room doors are opened while the laser is in
READY
mode.
Protective Housing
The laser has a protective housing that prevents unintended human access
to laser radiation. No sections of the protective housing can be easily
opened without special tools. This housing is to be opened only by a
Lumenis-certified technician.
Safety Shutter
The laser features a safety shutter that prevents the treatment beam from
exiting the laser. The safety shutter opens only when the laser is in ready
mode and the footswitch is pressed.
Manual Reset
If laser emission is interrupted during treatment (e.g., main electrical
power loss), the laser automatically turns
Off
. To resume treatment, you
must manually restart the laser using the main
On
/
Off
button.
Electronic Fault Detection Circuitry
If any of the electronic system monitors detect a fault condition, laser
exposure cannot occur. The high voltage power supply disables, the safety
shutter closes, and the footswitch disables.
Safety Interlocks
The laser has a safety interlock on the fiber optic laser connector.
