NOTE: If you train without your Suunto heart rate monitor, ACT CLASS may decrease, even though you have trained at the described level. We therefore recommend you train with your Suunto heart rate monitor to ensure it understands and guides you correctly.

Your Suunto heart rate monitor increases or decreases your activity class according to your training history. In both cases, you are asked to confirm the change before the setting is modified.
