3. This product and the Zepp App are not medical devices and cannot be used for medical purposes, or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell. 24-hour monitoring of heart rate and blood-oxygen saturation (SpO₂) need to be enabled in the Zepp App. For heart rate monitoring, the user must enable Auto Heart Rate Monitor in the Zepp App, and the minimum value can be set to 1 minute. Abnormal heart rate alerts and the preset value need to be set in the Zepp App. To measure blood-oxygen saturation (SpO₂), please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. SpO₂ alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement. The 24-hour stress level monitoring needs to be enabled on the watch or in the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for the breathing exercise need to be enabled on the watch. Smart health alerts need to be enabled in the watch settings or Zepp App. To process the one-tap measurement and other manual metric measurements, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.

According to the ISO 22810:2010 standard, the Amazfit Active 2 (Round) achieves a rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore suitable for splashes, snow, showering, or swimming. It has passed third-party testing conducted by SGS, and the report number is SHES241102180871. Remove the watch when taking a hot shower or trip to the sauna, since too much steam can affect the seal and make it less water-resistant in future.
