Explanation
Most users (99%+) should use Setting1.
Please select Setting2 if you have a very low heart rate,
for example if you are a professional endurance athlete.
In very rare cases you may get a higher heart rate reading
than you would expect while running at a low cadence.
Setting2 corrects that issue.
