In normal state, the radar will accurately judge the human body's sedentary state and the existence of sleep, and output information such as falls, breathing, and vital signs.

Phenomenon 1) The radar scanning area is large, and the movement of the doorway and the next door of the wooden wall is detected

             Adjustment method: reduce the radar sensitivity, and the radar provides scene settings.

Phenomenon 2) The underside of the radar is facing the running air conditioner and fan

             Adjustment method: Adjust the radar position, do not directly face the air conditioner or fan.

Phenomenon 3) Object shaking caused by air-conditioning wind

             Adjustment method: cotton, non-metallic items will not cause false alarms. Metal items need to be secured.

Phenomenon 4) The radar is not fixed, and the vibration causes false alarms

             Adjustment method: Avoid support shaking and vibration.

Phenomenon 5) Occasional moving objects such as pets and birds

             Adjustment method: Since the radar measures fretting and has high sensitivity, this interference cannot be ruled out.

Phenomenon 6) Power supply interference, resulting in occasional misjudgment

             Adjustment method: try to keep the power supply current stable and reduce the ripple.
