You can use the Dexcom Share feature with your t:slim X2 insulin pump. The Dexcom CGM system communicates directly to the Dexcom app, even when it is paired with the t:slim X2 pump.
The Dexcom CGM system can be paired with one medical device and one non-medical device at the same time. For example, the Dexcom CGM can connect to your t:slim X2 pump and a mobile device while running the Dexcom app. However, you cannot connect the Dexcom CGM to both the pump and the Dexcom receiver at the same time. Remember to pair your Dexcom CGM with your pump before pairing your CGM with the Dexcom app.
Always refer to the User Guide for important safety information and detailed step-by-step instructions on your t:slim X2 pump with Dexcom CGMs. Please consult the applicable user guide and refer to the table of contents.
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 such as loss of connection (on pump only) and the invalid pairing code (Alert 29) on pump only.
For all other CGM issues, including would not accept calibration, the sensor failure during the 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.
