How to Identify the left/right pumps
To ensure your breast pumps are correctly recognized as left or right, when you connect them in an Independent or Synchronised session the application will invite you to press the “+” button of the pump placed on your left breast (as in the photo below) to manually assign the correct side to each pump.
If you wish to change sides during your session, you can do this from “Options” ⇒ “Switch L/R”.
