These laser beams cannot be seen by the human eye. Should the beams enter the eyes,
they may be seriously damaged, resulting in excessive deterioration of eyesight. To
prevent such accidents, the following points must be strictly observed.
•
Never emit laser beam if no optical fiber is connected to the emitter section.
•
When disconnecting the optical fiber from the emitter section, stop emission first.
•
While laser beam is output, never stare into the emitter section nor the end of the
optical fiber that is connected to the emitter section.
Do not disassemble or modify the instrument, since high-power laser beams may be output
when doing so.
