Hear monitor doesn't work! It is ON but never worked! Watch is 2months old!

Are you sure it is an HR model? Are there LEDs on the back and when you press down and go to About does it say "Cardio" at the top? When you go to Sensors>Heart is it set for On and not External?

I hope this helps answer your question. If so, please mark it as a solution so others can look for it if they have the same question.

It gives me the option to switch on the sensor and it measured my heart rate once for a very short period .. see attachment
