Nov 12, 17 8:57. Post #6 of 7 (13366 views) I had the same issue on several straps but solved it. Put on the heart rate monitor strap. Go into settings on the receiving unit. scroll down to heart rate. Your unit has to reconnect again with HRM. Of course this will only work if you have good batteries.
It also seems that even when the heart rate monitor is "functioning" the stress and body battery readings are completely thrown off. I have invested a lot in garmin over the years, but I am very disappointed with this current lack of performance. Please help, before I am forced to start exploring the world beyond Garmin!

HRM-Tri just stopped working. Hi all, I’ve had the chest strap for less than a year and suddenly it just stopped working. I changed the battery as I assumed it was that, but it is still not working. I noticed a little brown (rust?) spot under the battery right by the green board (?) and suspect something internally crapped out.
