About the Watch

Charging the Watch

1. Connect the watch's charging cable to a power adapter or a computer's USB port.

Disassembling and Assembling the Watch Strap

Please refer to the illustrations to disassemble or assemble the watch strap.

Wearing the Watch

1. 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.
2. When measuring blood oxygen saturation, wear the watch correctly. Avoid wearing the watch on the wrist joint, keep your arm flat, maintain a comfortable (appropriately tight) fit 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.
3. We recommend that you tighten the watch strap during a workout and loosen it afterwards.
