So, this is the SECOND time in the past two months that we’ve had the “ERR121” error and Dexcom doesn’t seem to know what’s causing it. Now we won’t get a new receiver until TUESDAY because their shipping department doesn’t work on weekends (which sucks, because as you all know, our son happens to be SICK atm.)
I wish they’d figure out this error!
The guy I talked too on the telephone said he was Type 1 himself and uses the same unit. He recommended, when we’re changing out the sensor to “stop sensor”, but do NOT “shutdown”…just leave it running. He said he hasn’t had the ERR121 error, and he also doesn’t shut down the machine, so he asked if we’d try that.
Does anyone have any other info on what could be causing this error? It gets irritating to receive a new receiver every month…
