Wear the watch strap not too tightly or too loosely, 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 aected 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 exercise and loosen it afterwards.
