Dex went swimming with DS the other day. We thought it was ruined. I posted and got lots of great advice from this board. We covered the receiver in rice for two days, plugged it in, hit the reset and it turned on and initialized. We calibrated a new sensor and it's working great! I am absolutely amazed! Thank you everyone for all the great advice. I never imagined it would ever work after swimming for almost an hour. This affirms what I've suspected. I don't think I'd make it through diabetes without all the support and advice I get from CWD.
