• For higher accuracy and quicker responses to changes in your heart
rate, we recommend using a compatible chest heart rate sensor such as
Suunto Smart Sensor.
WARNING: The optical heart rate feature may not be accurate for every
user during every activity. Optical heart rate may also be affected by an
individual's unique anatomy and skin pigmentation. Your actual heart rate
may be higher or lower than the optical sensor reading.
WARNING: Only for recreational use; the optical heart rate feature is not
for medical use.
WARNING: Always consult a doctor before beginning a training program.
Overexertion may cause serious injury.
WARNING: Allergic reaction or skin irritations may occur when products
are in contact with skin, even though our products comply with industry
standards. In such event, stop use immediately and consult a doctor.
