If the Auto-Off Alert is turned on in your pump, it may cause you to experience an Auto Off Alert and/or Alarm when you are not expecting it — which will stop all insulin delivery.
If you have Auto-Off turned on, tapping 1-2-3 to unlock your pump will reset the Auto-Off timer to avoid receiving this alert.
Note that an interaction with the t:connect mobile app does not count as an interaction with the insulin pump.
