I had remembered this from the past and although we don’t use the PDM anymore, I did a bit of searching and found a couple posts where it was briefly discussed. > [@In the past 36 hours](https://forum.fudiabetes.org/t/in-the-past-36-hours/5904/6): > > Must be something in the air! I hope things get better for you soon! Oh, and as an aside, with the ‘battery’ issue…make sure you do NOT change it mid-session. slight_smile We changed our batteries once with pump installed and when we tried to turn it back on, we received an error.
