Operational and Safety Check, Topic 3.7, is an operational check of the system. It confirms that the system
turns on properly, responds properly to operator inputs, delivers the multiplexed YAG beam into the center of
an attached fiber, and provides an adjustable aiming beam through the fiber. It also confirms that the proper
fault messages are displayed when various connectors (i.e., footswitch and remote interlock plug) are
disconnected and the system is prevented from firing.
Periodic Maintenance, Topic 3.8, provides information on periodic maintenance checks to ensure optimum
performance of the system.

3.1.2 Safety Precautions
Lethal voltages and laser emission are the primary dangers to the servicing engineer. In addition to the
general safety precautions which always apply when working on electronics and lasers, the servicing engineer
must be aware of the following specific precautions:
• Only Lumenis certified VersaPulse PowerSuite YAG service engineers should attempt
any service on this system.
• Even with the keyswitch and the breaker in the “OFF” position there are lethal voltages
present inside the console. Always disconnect the main electrical service before working
on the console.
• Storage capacitors inside the system are capable of holding a lethal charge, even after
power has been removed from the unit. A charge level indicator LED located on the Sim-
mer/Start Control PCB flashes at a rate proportional to the level of charge on the main
charging capacitor. The LED can be seen through a small access window on the High Volt-
age Power Supply cover next to the Controller PCB. Do not rely on this indicator to deter-
mine that the main charging capacitor has been discharged. Before contacting the main
charging capacitor, disconnect the system from the primary power.
