B. When testing the heart rate monitor, let your hands stay parallel to the ground to prevent light leakage.

C. If you charge the bracelet for the first time, and there is no response after more than half an hour after charging, keep it charged for more than 4 hours to operate.

D.  Blood pressure and  heart rate working principle:

 The principle is the photoelectric transmission measurement method. In principle, when the sensor in the wristband makes contact with the skin and emits a beam of light, it measures the reflected/transmitted light. The blood absorbs light at a specific wavelength, each time the heart pumps blood, the wavelength is absorbed in large amounts. The wristband combines green LED light with a photosensitive photodiode to measure the amount of blood circulating at the wrist at a specific time to obtain heart rate information.
