How the Transmitter Works

The transmitter receives audio input from various sources such as phones, computers, microphones, or mixers. It then modulates this audio onto an FM radio frequency, which can be received by any standard FM radio or car radio within the transmission range.

8. Troubleshooting

If you encounter issues with your transmitter, consider the following common problems and solutions:

• No Power: Ensure the power cable is securely connected to both the transmitter and a working power outlet. Check the power switch.
• No Signal/Weak Signal: Verify the antenna is properly connected and installed in an optimal location. Ensure the selected frequency is clear and not interfered with by other broadcasts. Check RF power settings.
• No Audio Output: Confirm the audio input cables are correctly connected to both the source and the transmitter. Check the audio input level on the transmitter and the volume on your audio source.
• Distorted Audio: Adjust the audio input level to prevent over-modulation. Ensure the audio source is providing a clean signal. Check for proper stereo/mono settings.
• Overheating Warning: Ensure the cooling fan is not obstructed and the transmitter has adequate ventilation. Operating in extreme temperatures can trigger this warning.

For persistent issues, refer to the detailed user manual included in your package or contact customer support.
