Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam or view directly with optical instruments. Viewing the laser output with
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance
of 100 mmmay pose an eye hazard.Use of controls oradjustments or performanceof procedures other
than those specified may result in hazardous radiation exposure.
