Have you tried calling Roger? He's been very helpful to us when we've
had difficulties. 717-229-2221...I think that number is still good. He
has a great trouble shooting newsletter/manual type "thing".
Generally, you're going to need a new battery in either the monitor,
the transmitter, or both. OR, you may have a "crack" or exposed wire
in the lead, OR the electrode patch is torn, OR you need to apply
(more) gel, OR you need to tighten your girth to get good contact, OR
you have your leads switched (Red is Right..girth), OR you need to
check placement of the electrode patches. I've made all the above
"errors".
Hope this helps
BTW, I'm really sorry about your horse. It must have been unexpected
if you had just purchased the HRM. It is so difficult to loose an
animal companion. I'm glad you're back in the saddle. Good luck.
