Hi all!
Had no issues with my HRM-Tri for half a yeaar. Several days ago i found that my fenix 5 could not connect to strap. Changed battery and HRM TRi started working. I did one run session about 40 min and next day i could not connect to strap again. I again changed battery and strap started working. HRM case looks like new, without damages. No water inside.. Any ideas?
Thanks,
