7. Troubleshooting
- No Power: Ensure the USB-C cable is securely connected to both the intercom unit and the power adapter, and that the adapter is plugged into a working wall outlet.
- Poor Sound Quality/Feedback: Ensure intercom units are not placed too close to each other, as this can cause audio feedback. Obstacles like thick walls or metal structures can also affect signal clarity and range.

- Monitored Function Stops: The monitored function automatically deactivates after 24 hours. Reactivate it by pressing the MONITORED button and the desired channel again.
- Difficulty with Full-Duplex: While designed for full-duplex, ensure clear speaking directly into the microphone. Environmental noise can sometimes affect voice activation in certain modes.
