1.The probe has high sensitivity, no radiation, low ultrasonic power, safety, and high accuracy.
2.A large LED display screen can clearly show fetal heart rate, battery capacity, and volume.
3.Insert the 3.5mm 32 mono or dual channel headphone jack into the headphone jack of the device to listen to fetal heart sounds. At the same time, the device's external speakers will be turned off and there will be no sound output.
4.After hearing recognizable and rhythmic fetal heart sounds, keep the probe stationary for at least 5 seconds so that the device can accurately measure and display fetal heart rate.
5.The machine does not include batteries and requires self purchase.
