Optical heart rate measurement from the wrist is an easy and convenient way to track your heart rate. Best results for heart rate measurement may be affected by the following factors:
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.
Only for recreational use; the optical heart rate feature is not for medical use.
Always consult a doctor before beginning a training program. Overexertion may cause serious injury.
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.
