Thanks for info. I had Animas duration set to 4 hours but had noticed that my crashing lows often occurred at 5 hours. So on Tandem, set duration to 5 hrs. Have tried to turn on touch screen Dexcom, been on phone with Tandem and Dexcom, so I know I have been doing it correctly. However, it is not working, at first ‘sensor error’ with new sensor, now it just says ‘no readings, use meter’. The Dexcom tech #3, told me to drink water, chill and call back if still not working after 3 hours. Waiting for tech #1 to call on Tuesday, and tech #2 , says she will call me tomorrow morning.
At this point, I feel like I need to see official Tandem trainer instead of pump lady in office. Will call tomorrow to see what I can arrange. I need a new beginning.
