TomTom Runner watch
hi, guys. i'd like to know if this model measures the heart rate just by the bracelet, and if it does how do i make it work? Cause i did all the steps as the manual told me to do, but for some reason it doesn't start to measure the heart race. Do i need to get a tape for the chest area to synchronize with the watch? Cause i thought it would work out just with the bracelet.
