Troubleshooting

Problem	Solution
No power/device not turning on	Ensure the transmitter is fully inserted into the car's cigarette lighter socket. Check if the car's cigarette lighter socket is functioning (e.g., by testing with another device). Verify your vehicle provides 12-24V power.
Static or poor audio quality	Find a completely unused FM frequency on your car radio and the transmitter. Avoid frequencies close to strong radio stations. Adjust the volume on both your phone and the transmitter. Ensure your phone is within Bluetooth range of the transmitter. Try moving the transmitter slightly within the socket to improve signal.
