The heart rate monitor watch should be worn slightly more tightly around your
wrist when working out.
During very intense workouts or other activities, which cause forceful or
arrhythmic movements of your wrist, the sensor may not be able to measure
your heart rate correctly.
If your heart rate monitor watch does not display your heart rate, relax your
wrist and remain motionless for a short while (approximately 10 seconds). Your
heart rate should now appear.
