The infrared sensor of Jiaming Watch will generate a series of data according to the heartbeat, and the flashing green light means that the data transmission is normal. In other words, when the wearer's heart rate and blood oxygen level are normal, the watch will flash green to remind them of their health.
If this function does not stop within a reasonable time, it is recommended to contact a professional maintenance point or Jiaming after-sales department for consultation. If it is within the warranty period, you can find after-sales maintenance or replacement.
