    DEVICE EVAL OF MONITOR (B)(4) HAS BEEN COMPLETED. UPON INVESTIGATION THE MONITOR WAS RESETTING. THE CAUSE FOR THE RESETS WAS ISOLATED TO AN INTERMITTENT BGA SOLDER CONNECTION AT THE U500 DSP COMPONENT ON THE MONITOR C/A BOARD. THE ROOT CAUSE FOR THE INTERMITTENT BGA CONNECTION AT U500 COULD NOT BE POSITIVELY IDENTIFIED, BUT THE DAMAGE LIKELY RESULTED FROM THE MONITOR IMPACTING A HARD SURFACE. ROOT CAUSE ANALYSIS OF SIMILAR EVENTS FOUND THAT EXCESSIVE STRAIN ON THE PRINTED CIRCUIT ASSEMBLY (PCA) FROM SEVERE IMPACT CAN CAUSE FRACTURED SOLDER CONNECTIONS. A MECHANICAL DESIGN CHANGE TO REDUCE THE PCA STRAIN WAS APPROVED BY FDA ON (B)(4) 2012. IMPLEMENTATION BEGAN (B)(4) 2013. RESULTS WILL BE MONITORED. NO ADVERSE EVENT RESULTED FROM THE DEFECTIVE MONITOR. THE LAST PT TO USE THIS MONITOR DID NOT REPORT ANY DEFICIENCIES.
