Changing Batteries in PDM caused POD error?

This may be related to what @Eric discussed a while back:

Yet another Omnipod PDM failure

You should plan your battery changes for when you change your pod (not every time you change your pod, but just when the battery is low). The only thing wrong with your PDM is the internal battery is bad. The internal battery is only used to maintain date and time when you change batteries. I have a PDM like that, but I haven’t had it replaced. When the battery indicator shows it is low, I just change the batteries at pod change time. Anyway, this would be worth mentioning to people starting…

Before then I changed my batteries whenever the display showed they were getting low, but since that warning I’ve superstitiously changed them only after deactivating a pod.
