It was reported that during the pt's office visit that the pt's magnet activations were not displaying correctly.It was reported that the pt only had one magnet swipe recently, with only a total of 8 registering.However, for the one activation on (b)(6) 2014, the tablet magnet history was displaying 15 times.The total swipes registered displayed as 86.A copy of the physician's programming tablet data was obtained.Magnet history coincides with only one swipe registering on (b)(6) 2014 with no indication of multiple magnet activations.It was observed that total operating time rollover of the device occurred between the last appointment on (b)(6) 2012 and (b)(6) 2014.As a result, the magnet history on the tablet was showing 15 activations on (b)(6) 2014, because no other activations were available in the history due to rollover.The 15 most recent magnet activations stored within the generators memory span the time period before/after the rollover event are displayed and since there was only one swipe, 15 activations were displayed on the tablet on (b)(6) 2014.It is known that the device reed switch can be activated by several consumer devices/other devices that have magnetic field (i.E.Multiple accidental magnet swipes, etc.).However, attempts for further info from the physician were unsuccessful.
