    Additional Manufacturer Narrative · 1

    DEVICE EVAL SUMMARY: DEVICE EVAL OF MONITOR SN (B)(4) HAS BEEN COMPLETED. THE REPORTED PROBLEM (WILL NOT POWER UP) HAS BEEN CONFIRMED. AS RECEIVED, THE MONITOR WOULD NOT POWER ON. THE CAUSE OF THE MONITOR NOT POWERING ON WAS A FLASH MEMORY FAILURE (COMPONENTS U102 AND U105) ON THE C/A BOARD. THE FLASH MEMORY HAD AN INTERMITTENT BGA CONNECTION, WHICH WAS DISCOVERED THROUGH THE USE OF A TARGET MEMORY TEST. THE INTERMITTENT CONNECTION IS LIKELY DUE TO A FRACTURED SOLDER CONNECTION INDUCED BY MECHANICAL STRESS. THE EXACT SOURCE OF THE MECHANICAL STRESS HAS NOT BEEN POSITIVELY IDENTIFIED BUT THE FRACTURED CONNECTION MAY HAVE BEEN ACCELERATED THROUGH ROUGH HANDLING. NO ADVERSE EVENT OCCURRED AS A RESULT OF THE DEFECTIVE MONITOR. THE PT RECEIVED A REPLACEMENT MONITOR.
