Module No. 3515
Measuring Your Blood Oxygen Level
Important!
It may not be possible to obtain blood oxygen level measurement results if you are in a cold location and your wrist is cold. Warm your wrist before attempting measurement.
If measurement at the same location on your wrist fails continuously or if measured values fluctuate widely, change the location on your wrist where you are wearing the watch. You can also try moving the watch to your opposite wrist for measurement.
Take several measurements under identical conditions, moving the watch around your wrist. Find the wrist location where measurement is most stable.
Do not take measurements immediately after exercising. Wait until your breathing stabilizes.
During measurement, keep your arm still and do not move it.
During measurement, refrain from talking and do not hold your breath.
