Wear the watch strap neither too tight nor too loose, and leave enough space
for the skin to breathe. This makes you feel comfortable and allows the sensor to
function.
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. 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.
We recommend that you tighten the watch strap during workout and loosen it
afterwards.
