Wearing the Watch

1. Wear the watch strap neither too tight nor too loose, leaving enough space for the skin to breathe. This ensures comfort and allows the sensor to function properly.
2. When measuring blood oxygen saturation, wear the watch correctly. Avoid wearing it on the wrist joint, keep your arm flat, maintain a comfortable (appropriately tight) fit between the watch and your wrist skin, and keep your arm still throughout the measurement process. External factors (arm sag, arm sway, arm hair, tattoos, etc.) can lead to inaccurate results or measurement failure.
3. It is recommended to tighten the watch strap during workouts and loosen it afterwards.
