Pairing your pump and Guardian™ transmitter


Device: MiniMed™ 780G insulin pump

Before you can start using your sensor, you must first pair your pump with your transmitter so they can begin communicating with each other when they are wirelessly connected.

You can pair only one transmitter with your pump. If you already have a transmitter paired with your pump, you must delete it before continuing.

Please note: if you use the Guardian™ Sensor 3, your Guardian™ Link transmitter will look slightly different, but the instructions remain the same.


To pair your pump and transmitter:

  1. Attach your transmitter to the charger and make sure the transmitter is fully charged. Keep your transmitter attached to the charger.

    Note: Both lights on the charger are off when the transmitter is fully charged. For more information, see the transmitter user guide.
