See the attached pictures. Thursday night at 22:02 it has stopped working with the heart rate measurement. I restarted the watch, connected to the charge cable and nothing. Friday I got no HR the whole day, since the Thursday event. Then on Friday before bed I put to charge overnight, when I wake up Saturday morning it started working again. It was fine the whole day! But then 22:02 guess what happened again? Yes, the HR led is dead again, trued charging again and nothing. Today Sunday morning no HR. How is that possible? I am so furious because I am traveling and without my HRM-PRO belt and in the middle of a HM training. Software version 18.23, Forerunner 265.
