The wrist heart rate on my Forerunner 325 will not activate when I go to running mode. The little heart symbol just stays flashing and will not go green. The 325 will give my resting heart rate ok when I press the down button from the time of day screen, so I know the hrm is working. The green LED lights on the back are on to start with but after a while once in running mode, they go out. It all worked fine up to 3 June 2016 but for the last week it has not recorded my heart rate when running.
