5. Troubleshooting
If you encounter issues with your Uniden USB-C to RJ11 Power Cord, refer to the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radar detector does not power on. | Loose connection, vehicle USB-C port not active, or faulty cable/detector. | Ensure both the USB-C and RJ11 connectors are firmly seated. Check if the vehicle's USB-C port is active (e.g., by testing with another device). Test the radar detector with its original power cord if available. |
| Intermittent power to radar detector. | Loose connection, damaged cable, or unstable power from vehicle port. | Check all connections for tightness. Inspect the cable for visible damage (frays, cuts). Try a different USB-C port in the vehicle if available. |
| Cable does not fit into port. | Incorrect port or obstruction. | Verify you are using a USB-C port in the vehicle and an RJ11 port on the radar detector. Check for any debris in the ports. |
