To disconnect your CGM from your t:slim X2 pump, please follow these steps:
Navigate to Options > My CGM > Stop Sensor
NOTE: It will take up to 24 hours for the graph to disappear. A user may also reboot the pump and that will remove the graph and stop all communication with the transmitter immediately.
During this 24-hour period, the pump will be searching for the transmitter and can partially or fully deplete the pump battery. It is important to carefully watch the battery during this time if you choose not to reboot your pump.
Important note about Dexcom support:
Dexcom and Tandem have agreed which system issues are best handled by each company, including which company is responsible for reporting those events to the appropriate regulatory authority. To help ensure that the required reporting takes place in a timely fashion, customers may need to contact Dexcom for some issues and Tandem for others.
Tandem handles issues with the connection between your Dexcom transmitter and t:slim X2 pump, questions about calibration, the “---” display, and sensor failures after the 2-hour warmup period.
For all other CGM issues, including the sensor failure during the 2-hour warmup, “no restarts” alert or physical problems with your sensor or transmitter, such as bleeding, bruising, skin reaction, adhesive issues, applicator issues, or broken wires, you should contact Dexcom using one of the options at dexcom.com/contact.
