IR2304 - Safety upgrade for DXRs with the optional fiber probe


The existing interlock circuits of the DXR are not correct when set for Class IIIb (fiber probe) operation. This was corrected on April 8, 2009. All Class IIIb DXR systems that shipped before April 8, 2009, must receive this update to ensure the safety of the customer. If a field install of a fiber probe is made on a system that shipped before April 8, 2009, then the fix will need to be installed at that time.
