Connecting Dexcom G6 CGM to Your Replacement Pump

Whether you are continuing a current Dexcom G6 continuous glucose monitoring (CGM) session or starting a new one with your Tandem Diabetes Care replacement pump, you will need to disconnect your old pump from your transmitter and connect the new one by following the steps below:

  1. Write down your current transmitter ID number, as you'll need it for your replacement pump. You can find your transmitter ID in either your old t:slim X2 insulin pump (tap OPTIONS and then My CGM) or within the Dexcom G6 mobile app (tap Settings)
  2. Do not stop the sensor session on your old pump
  3. Place your old insulin pump into Storage Mode
  4. Enter the transmitter ID into your replacement pump
  5. Start your sensor on your replacement pump
  6. Skip the sensor code on the replacement pump

Dexcom G6 and Transmitter ID Screens. Note: Not all screens are shown.

It may take a few minutes for the sensor and replacement pump to connect and for CGM values to populate on your t:slim X2 insulin pump. The antenna symbol to the right of the battery indicator should be white.
