How do I use the BabyNera?
How do I use the BabyNera?
STEP 1: Prepare the Device
- Insert 2 x AA batteries into the BabyNera doppler.
- Connect the probe wire securely to the main device.
- Lie down comfortably on a flat surface, facing upward.
- Expose your lower belly, as you would during a regular ultrasound.
- Tip: Having a full bladder can sometimes help amplify the heartbeat.
STEP 2: Apply Gel & Power On
- Switch on the device using the power button.
- Apply a generous amount of ultrasound gel to reduce static and improve sound clarity.
- Gently place the probe on your lower abdomen and begin moving it slowly to locate the heartbeat.
STEP 3: Locate the Heartbeat
- Start just above the pubic bone and move the probe slowly upward.
- Rock or glide the probe gently, covering different angles until you find the heartbeat.
- If no heartbeat is found, don’t worry—try again later or wait for the baby’s position to change.
- Once found: view the BPM (beats per minute) on the display.
- Adjust volume using the built-in controls.
- You can also switch between BPM display and curve mode.
STEP 4: After Use
- Turn off the device and clean the probe using a cloth or wipe.
- For thorough cleaning, you may use 70% ethanol, then let it air dry.
Not detecting a heartbeat? Here’s what to do.
Not detecting a heartbeat? Here’s what to do.
If you’re having trouble picking up a heartbeat, don’t worry—it’s common, especially in early pregnancy. The heartbeat can be faint or move depending on baby’s position. Try the steps below:
✅ Tips to Improve Detection
- Search low on the belly, just above the pubic bone.
- Move the probe slowly, pausing every few seconds.
- Try at different times of day, as baby’s position can shift.
⚙️ If You See ~130 BPM but Hear Nothing
The device may display a temporary placeholder (around 130 BPM) while searching. Once the real heartbeat is found, it will automatically update—usually within 15 seconds.
🔧 Troubleshooting Steps
1. Unplug and re-plug the probe to ensure a proper connection.
2. Use enough gel to avoid interference.
3. Move the probe slowly from the lower belly upward.
4. Hold still once you hear the heartbeat—wait 15–20 seconds for BPM to stabilize.
5. Expected BPM range: typically 120–160.
6. Keep probe and main unit slightly apart when powered on.
7. If readings are unstable, gently shift position to locate a clearer sound.
✅ Test the Device
To check if the doppler is working, place it over your own heartbeat (left chest area, not wrist). If it reads and plays a steady BPM, the device is functioning properly.
