Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal on Parent Unit | Camera is out of range or not powered on. | Move the Parent Unit closer to the Baby Unit. Ensure the Baby Unit is plugged in and powered on. Re-pair if necessary (refer to manual for pairing instructions). |
| Poor image quality | Low light conditions, interference, or camera lens is dirty. | Ensure adequate lighting or rely on night vision. Reduce interference from other 2.4GHz devices. Clean the camera lens with a soft cloth. |
| Low volume from Parent Unit | Volume setting is too low. | Increase the volume using the dedicated buttons on the Parent Unit. |
