Hrm strap not connecting!

My garmin tri HRM is not connecting or picking up to my tax neo!
Is anyone has this problem and how could I fix it?
Thank you

Does the strap have its own integral battery if so like my POLAR HRM may need swapping

I think has a normal battery in!
I don’t know!
What I have to swap to?
Thank you

What are you running Zwift on, therefore trying to connect it to?

I think the Tri-HRM is only ant+ so it will only be picked up by an ant+ dongle if running on a laptop. It won’t be compatible with AppleTV. You would need to get a bluetooth (or dual band) HRM.
