Heart rate is not out of value

Check whether the sensor on the back of the watch has green light when measuring heart rate
1. If there is no green light, please follow the after-sales process
2. If there is green light, but the value is often not given or the value is not accurate, please wear it correctly. Measurement: put the arm flat, and the watch is worn at a finger away from the wrist bone. Relax and keep still, and ensure that the equipment is close to the wrist
Note: when worn correctly, individual differences such as skin color, hair, tattoos and scars may also affect the measurement accuracy. The value measured by the watch is only for reference and cannot be used as a basis for medical diagnosis
