A few months ago, my daughter’s Dexcom G5 receiver was caught in a reboot cycle. The unit would vibrate, the ‘boot-up’ screen would come up, and then turn off. The cycle would repeat every 90 seconds. Resetting with a paperclip did not stop this. We called Dexcom and they shipped out a replacement as the receiver was still under warranty.
Last night, the same reboot loop issue happened again. When calling Dexcom, the representative said it was a known issue that if you stop a sensor session and then turn off the receiver within 15 minutes of stopping the sensor, the unit can get caught in this reset loop. This is exactly what had happened to my daughter. Her sensor had come off at bedtime, and she was going to insert a new sensor in the morning, not wanting to stay up another two hours to wait for calibration. Turning off the receiver to save battery was mistake I guess.
So - just an FYI for anyone else using the G5 receiver.
