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.
