| Issue: | The MRx could contain incorrect internal software settings, causing the following two issues: 1. The device will perform the weekly automated tests hourly, which could cause the therapy capacitors to degrade sooner than intended. 2. While connected to AC or DC power and with no battery installed or the battery installed has a charge level of less than 10%, the Ready for Use (RFU) indicator will not provide the expected low battery indication (flashing red X with audible chirp). Instead, the RFU will show a flashing black hourglass, indicating that sufficient battery power is available for device operation. |
