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 mm may pose an eye hazard. Use of controls or adjustments or performance of
procedures other than those specified may result in hazardous radiation exposure.
Warning
The laser is active when the card is booted and the safety key is in the on position (labeled 1). The
port does not have to be in service for the laser to be on. The laser is off when the safety key is off
(labeled 0).
