Note: Utility Loss Notifications for Wi-Fi devices are dependent on the router communicating with Mobile Link during that outage as well as the router sending that information over.

In the below image, the generator began exercising at 02:01 PM, and then returned to "Ready to run" status at 02:06 PM. This means the generator exercised for 5 minutes. The beginning of the "Ready to run" event indicates when the previous event stopped. Mobile Link does not show an "end of run" time stamp indicator.
