If you are having difficulty keeping your Dexcom CGM connected with your t:slim X2 insulin pump, it may be because:
- Your CGM and pump can’t “see” each other. For best connectivity, the pump and CGM should be within line-of-sight without any obstruction (including any body parts). Ensure that your pump and CGM system are on the same side of your body and that your pump screen is facing away from your body.
- Your Dexcom G7 is linked with a Dexcom receiver instead of your t:slim X2 pump. A single Dexcom CGM system cannot be connected to your insulin pump and a Dexcom receiver at the same time. To help resolve the issue, please turn off your Dexcom Receiver.
- You received a new or replacement pump and the old t:slim X2 insulin pump is linked to your Dexcom CGM. A single Dexcom CGM cannot be connected to more than one medical device at the same time. To help resolve the issue, please turn off your old t:slim X2 insulin pump.
After trying any of the above tips, give your pump 10-15 minutes to reconnect.
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.
