A HRM or accessories folder would be best for this, there isn't one so it goes here.
My HRM-RUN heart rate monitor has stopped working. I changed the battery recently. There is some discolouration on the left hand snapper, under the plastic seal. It looks like some sort of corrosion or even rust.
Anyone have any experience or suggestions? ciq.forums.garmin.com/.../1292573.jpg ciq.forums.garmin.com/.../1292574.jpg
