Precautions for blood oxygen measurement
1.
Wear the watch a distance of one finger away from the carpal and remain still.
2.
Wear the band tightly, with an appropriate sense of pressure.
3.
Place your arm on a tabletop or a stationary surface, with the watch screen facing up.
4.
Remain still during measurement and focus on the measurement.
5.
Factors such as hair, tattoo, shaking, low temperature, and incorrect wearing of the watch may
affect measurement results, and even lead to measurement failure.
6.
The measurement range of the watch is 80%-100%. This feature is for reference only and
should not be used as a basis for medical diagnosis. If you feel unwell, please seek medical
advice.
Stress
The stress index is calculated based on changes in heart rate variability. It is a reference for health
status evaluation. You should rest more when the index is high.
Wake up the watch, press the upper button on the watch face page to go to the app list, and swipe
up and down to select and open the Stress app. In the Stress app on the watch, you can view your
most recently measured stress value, all-day stress status, stress interval distribution, and pressure
status over the last seven days. Synchronize the data to the app to view more information. Setting
the Stress app as a
widget allows you to easily measure your stress.
