How do I wear my A370?

A370 continuously measures heart rate from the wrist, in everyday-wear and during exercises. To get accurate heart rate readings, find a comfortable fit for your wrist by following these tips.

In everyday-wear, secure the wrist band on top of your wrist, behind the wrist bone. Do NOT place the fitness tracker on top of the wrist bone. The band can be slightly loose as long as the sensor on the back is touching your skin and stays in place when you move.

Tighten the band a little bit when you start a training session, so the sensor will not move when you exercise. The wrist band should not be uncomfortably tight either. Remember to loosen the wrist band after training for a more comfortable fit. 

Keep your wrist and A370 clean by washing, rinsing and drying them daily. Once in a while take the tracker off and let your skin breathe.
