The product is simple and convenient to use.
The product is small in volume and light in weight (including the battery, it weighs approximately 50g), making it convenient to carry.
■ Low power consumption, two AAA batteries can last for 10 hours.
When the battery voltage is too low, it may affect normal use, and the visible window will have a low voltage warning indicator.
The product will automatically turn off after 8 seconds when there is no signal.

Application scope: ward monitoring, home health care, patient detection, outpatient medical treatment.

Power Requirements: 2 AA 1.5V Alkaline Batteries (Batteries Not Included in Shipping)
