Letter states reason for recall, health risk, and action to take: Until the next version of instrument software is available Siemens recommends changing the software behavior from the current default of 2: Warning+STOP to 1: Warning. The behavior for the Warning setting is to display the test result as ERROR with a Safety(S) flag and generate a yellow warning in the Operators event log for each test result encountering a mix error. The instrument will continue to process samples. The flagged test must be repeated to obtain a valid result.
