How to Wear Redmi Watch 2 Lite
For daily use, comfortably tighten the watch around your wrist about one-finger width away from your wrist bone. Adjust the strap to ensure the heart rate sensor can collect data normally.
Note: Wearing the watch too loosely may impact the data collection by the heart rate sensor.
