Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Device not turning on. | Loose connection in car socket; car socket not providing power. | Ensure the device is firmly inserted into the car's cigarette lighter socket. Check if the car's socket is functional (e.g., by testing with another device). |
| Poor FM signal/Static noise. | FM frequency interference; car radio not tuned correctly. | Find a clearer, unused FM frequency on your car radio and match the transmitter's frequency to it. Avoid frequencies used by strong local radio stations. |
| Bluetooth not connecting. | Bluetooth not enabled on phone; device not in pairing mode; incorrect device selected. | Ensure Bluetooth is enabled on your phone. Restart both the phone and the FM transmitter. Forget the device in your phone's Bluetooth settings and re-pair. |
| Slow charging or no charging. | Cable issue; device not compatible with fast charging; multiple devices drawing too much power. | Try a different USB cable. Ensure your device supports the fast charging protocols (QC3.0, AFC, FCP). If charging multiple devices, total output may be limited. |
