Fetal Heart Rate Monitor Usage Instructions

Rotate the switch clockwise to turn on the device using the volume button. Gently locate the optimal probe position by hand, ensuring the probe is firmly pressed against the abdominal wall to obtain the best audio signal. Adjust the volume as needed. In late pregnancy, the fetal heartbeat position shifts upward. During pregnancy, ensure adequate rest, proper nutrition, and sufficient sleep; maintain a positive mood, avoid anger and irritability, and engage in moderate physical exercise.
