My Pump: t:slim & Dexcom G4



My 723 has developed a irritating little problem: every time (at least the last 3 times) I change the battery, it gives me a code A21 "Pump reset, settings saved". I then have to wait while it goes through a self test then I have to reset the date & time and then rewind and reprime (what is this, a stupid Ping? (IMG:style_emoticons/default/Tomato.gif) ).

It first happened about 45 days ago. I called MM at the time and the agent said that I probably removed the battery at just the wrong time. OK. Today, I changed the battery and it happened again. I reset everything and then said to myself "I wonder...". I removed and replaced the new battery and it happened again. I called MM and they are sending me a replacement pump.

By the way, all of my settings were preserved (except my vibrate alarm which I had to set) along with all of my using statistics. Just date & time and plunger position were lost each time.

I am curious, anyone else ever had this problem? I did a search here for "A21" and nothing came up.

tedm-
My only thought, and I would think MM would have already sugggested it, is the battery cap may be a problem. I have the 522 and was having a problem with the CGMS and MM sent me two new battery caps. That told me they knew they had a problem and several other IPF'ers have had the same problem. I think this was mainly with the 5 series pumps and not the 7 series.

Just to be clear: there was absolutely no problem while the battery was in the pump, only during changing the battery. Based on this, I don't think it could be the cap.

Thanks for the suggestion, anyway.
