  • What happens for an activity recording in progress when the device runs out of battery ? Is the recorded data lost ? Or will it sync upon charging the battery ?

    • Hi, Once device battery runs out further recording will not happen but all activity recorded up to that moment will be saved on the device and will sync up on charging

  • What does this reading indicate ?

    • I’m not a doctor. But, it looks like you just put on the device, you forgot to wet the pads, and you were moving too much while the strap wasn’t tight enough. At the 16 second mark everything looks normal. But I’d check to see if that J segment is normal for you.

    • My guess is the sensor was moved while you were wearing it. Try running an real-time “ECG” on your smartphone and then move the device and your body around and see how the graph reacts.
