Just bought a spark 3 watch from Amazon and heart rate monitor doesn't seem to work. Got it switched to on in settings but there is no reading. Just two little lines flashing and if it can't detect a heartbeat. I am definitely alive! Any reason why it's not working?

    Are you sure you have a Cardio version? Are there LEDs on the back and when you press down and go to About does it say "cardio" at the top? If so, is it set for internal under Sensor>Heart (it should say On, not External)? If it is not a Cardio model you will need to use an external strap to get HR.

    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.
