    Additional Manufacturer Narrative · 1

    A BECKMAN COULTER FIELD SERVICE ENGINEER (FSE) VISITED THE SITE AND EXAMINED THE SYSTEM. THE FSE FOUND THAT THE SYSTEM HAD POOR FLOW CELL PHASE ALIGNMENT. THE FSE REPLACED THE FLOWCELL, MAL SENSOR, AND SAMPLE LINE. THE FSE THEN PERFORMED A FLOW CELL PHASE ALIGNMENT WHICH RESOLVED THE ISSUE. SERVICE WAS VERIFIED FOLLOWING ESTABLISHED PROCEDURES AND THE INSTRUMENT CONFORMS TO PUBLISHED SPECIFICATIONS. THIS IS ONE OF TWO INDIVIDUAL MEDWATCH REPORTS BEING SUBMITTED AS TWO SEPARATE DEVICES WERE INVOLVED. REFERENCE MEDWATCH NUMBERS 1061932-2012-02847 AND 106-1932-2012-02848 FOR ALL ASSOCIATED REPORTS. THE SAME PATIENT SAMPLE IS INVOLVED IN EACH REPORT.
