RNING Use only non electrically conductive fiberoptic cables Use of conductive fiber optic cables will compromise the safety and effectiveness of this instrument WARNING High intensity light can cause burns to tissue even if the tip of the fiber optic cable or attached terminal device is cool Burns are caused by the absorption of light by tissue and the subsequent conversion of that light energy into thermal energy Full thickness burns can be caused by prolonged exposure to concentrated light energy Anesthesized patients and poorly perfused tissues are particularly susceptible to burn injuries via this mechanism There is serious risk of igniting fires if energized fiberoptic cables are placed on flammable materials IT IS THE USER S RESPONSIBILITY TO DETERMINE AND MAINTAIN THE MINIMUM SAFE DISTANCE BETWEEN THE END OF THE ENERGIZED FIBEROPTIC CABLE AND ANY LIVING TISSUE OR FLAMMABLE MATERIAL WARNING Intense light emitted from the ProXenon 350 Surgical Illuminator can cause permanent eye damage if viewed directly with unprotected eye The risk of injury is reduced by using the minimum level of illumination necessary by minimizing exposure time and by avolding close stationary viewing WARNING There is a risk of injury to tissue from exposure to the intense illumination Using light intensity settings in excess of that required for good visualization contributes to tissue warming and should be avolded WARNING Always have back up light so
