How to use:

Before using it for the first time, make sure 2 batteries are in

Press the power button to power on, then adjust the volume

Lie flat with a cushion pillow, keep legs straight and relax

Attach the fetal probe to the abdomen to locate the position of the fetus and find out the best direction to the fetal heart

After hearing regular fetal heart sound, the FHR value will display on the screen in real time
