    Additional Manufacturer Narrative · 1

    THE FIELD SERVICE ENGINEER (FSE) WAS DISPATCHED TO THE SITE ON (B)(4) 2009 TO INVESTIGATE THE EVENT. THE FSE INSPECTED THE INSTRUMENT AND FOUND THAT TWO OF THE FOUR REAGENT PIPETTORS HAD BEEN DISABLED. THE FSE INSPECTED AND CLEANED ALL REAGENT PIPETTORS, THE SAMPLE PROBE, ALL WASH STATION, DISPENSE PROBES AND WASH WHEEL. THE FSE REPLACED THE DUCK BILL VALVE, ASPIRATE PROVES AND PERI-PUMP TUBING. THE FSE CLEANED AND LUBRICATED ALL GUIDE RAILS. THE FSE RAN A HIGH SENSITIVITY SYSTEM CHECK AND A ROUTINE SYSTEM CHECK, BOTH PASSED WITHIN INSTRUMENT SPECIFICATIONS. ALSO, A TEN REPLICATE ACCUTNI PRECISION TEST WAS PERFORMED AND PASSED WITHIN THE ASSAY PRECISION CLAIMS. THE FSE VERIFIED ALL REPAIRS PER ESTABLISHED PROCEDURES AND ALL RESULTS MET PUBLISHED PERFORMANCE SPECIFICATIONS. ALTHOUGH SOME HARDWARE ISSUES WERE ADDRESSED BY THE FSE, A DEFINITIVE ROOT CAUSE COULD NOT BE DETERMINED FOR THIS EVENT. THIS REPORTABLE EVENT WAS IDENTIFIED DURING A RETROSPECTIVE REVIEW OF COMPLAINTS CONDUCTED BETWEEN JANUARY 1, 2008 AND OCTOBER 23, 2010 FOR ADDITIONAL REPORTABLE EVENTS.
