Can I change the battery myself?

Of course! Replacing the battery is easy and only takes a minute.

Follow these steps:

  1. Take Ulla off the silicone band.    
  2. Carefully remove the cap.
  3. Remove the battery and replace it with a new one, flat side facing away.
  4. Wait for Ulla to start blinking continuously for approximately 1 second.
  5. Put the cap back on.
  6. Clip Ulla back on to the silicone band.
  7. Ulla is ready.
