Problem
When measuring your Blood Oxygen Level (SpO2), the result is incorrect or inconsistent.
Troubleshooting Tip:
Make sure your watch is comfortably snug on your wrist, with the sensor completely touching your skin. Stay still until the measurement is complete, about 10-20 seconds. When the result displays, that is your real-time blood oxygen level.
You must be wearing the watch for your blood oxygen level to display.
