Connecting to Suunto smart sensor HRM
-
I’m having an issue with my Suunto Smart Sensor HRM. I can pair it with my watch without any problems. Via the Suunto app on my phone I can also find the smart sensor and add it.
However, when I start an activity, the watch still uses its built‑in optical heart‑rate sensor instead of the chest strap. The HR reading stops as soon as I take the watch off my wrist, which suggests the belt isn’t being used at all.
What is the correct procedure to verify that the Suunto Smart Sensor HRM is actually providing the heart‑rate data?
Manny thanks for any advice.
