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 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 exercise and loosen it
afterwards.
