I have a Fénix 3 with HRM-Run, the one that you can plug in and out chipset on the strap. Recently on each workout it stops after some time transmitting HR data to the watch. Then came back aleatory after some time. I replaced batteries, included keeping chipset alone without battery for 10 minutes as Garmin recommendation.
I think it’s time to change it for a new one, but I have the doubt if a new strap should go well or I must to change for a new full kit HRM-Run.
I mean you guys if anyone facing similar problems how they solved.
thanks I’m advance
