I am posting this here because I want to see replies directly to my question (rather than posting on the Animas group).
When I changed the battery in my Animas pump, all of a sudden the time changed from "am" to pm" - no reason for the time setting to change. I noticed it the next day when I used my pump to tell what time it was. I am glad I noticed fairly quickly (didn't think I had to check after the battery change process). This could have made for problems since I have different basal rates throughout the day and different carb to insulin ratios for the different times of the day. My plan is to keep tabs on things for a while since I am seriously considering getting a T-Slim. And so I don't want to replace my current pump and thus have a longer time to wait for the warranty to be over.
Has this happened to anyone else?
