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.

While seated, place your arm on a table or
