In order to ensure the accuracy of heart rate, blood oxygen, and
other measurements, please wear your watch at a distance of at
least one finger away from the carpal, and keep the strap at a
comfortable snugness.
During workout, please wear it as tightly as possible to ensure that
the watch does not shake. Wear your watch at a distance of at
least one finger away from the carpal to obtain more accurate
heart rate data. After workout, you can loosen the strap
appropriately to ensure a comfortable wear experience.
When measuring blood oxygen saturation, wear the watch correctly.
Avoid wearing the watch on the wrist joint, keep your arm flat, maintain comfortable (appropriately
tight) fitting between the watch and the skin of your wrist, and keep your arm still throughout the
measurement process.
05 Wearing the Watch
Note:
When affected by external factors (arm sag, arm sway, arm hair, tattoo, etc.), the measurement result
may be inaccurate or the measurement may fail and provide no output.
