What should I do if Mi Motion-activated Night Light 2 stays on after I install the battery?

Mi Motion-activated Night Light 2 is activated when it is powered on for the first time, it will turn on no matter during the day or at Night. It will automatically turn off after a period of time when it is placed in a position that cannot detect human movement. In the future, it will only be activated when it senses human movement in dark Light.If the night light continues to sense the human activity, the light is steady on ,it is a normal phenomenon of real-time induction.
