At this time, all Tandem Diabetes Care software updates are one-way. This means that you cannot revert to a previous software version after completing an update. For example, once you have updated your Tandem insulin pump from software version 7.6 to version 7.7, you cannot change your pump back.
If you have not yet completed the required training in the Tandem Source platform, you can contact Customer Techincal Support for assistance.
