What are the flashing green lights on the back of my Delvfire?

The flashing green lights are the heart rate sensors taking a reading. This happen periodically throughout the day/night when Automatically is enabled for the Heart Rate Detection option within the VeryFitPro app.

If you wish to stop the green lights from flashing, you can simply switch the heart rate detection option from Automatically to Manually.

To do this..

1. Open the VeryFitPro app
2. Tap Device from the menu at the bottom of the app
3. Scroll to Heart Rate Detection and tap where it says Automatically
4. Tap Manually and then tap the tick button (top right of the app) to confirm your selection

By switching from Automatically to Manually a HR reading will now only be taken if you navigate to the HR option on the tracker itself or from within the app from the Mainpage > Heart Rate section.
