So here goes! There is actually one thing you have to check before you start the solution below!

The check is to see if your H7 still works and has enough battery juice! Now that is easy! Don’t mind me saying that it is absolutely crazy that the H7 does not have a simple battery check in it. But then again, who am I to come up with these practical idea’s 🙂

So pick up your smartphone and within the settings of your smartphone look for bluetooth. Found it? Connect the H7 to the chest strap! Then go search for another bluetooth device. Does the H7 band show up? Great, there is still battery juice! So no problem there.

Doesn’t the H7 show up, then this could mean two things.


  1. Your phone is to old and it cannot find this new piece of technology, go buy a new phone!
  2. The Battery is dead! Go buy a new Battery!
