Operating Instructions
- Power On: The transmitter powers on automatically when connected to a USB Type C power source. The LCD display will illuminate.
- Adjust Frequency:
- Use the Up (▲) and Down (▼) buttons to adjust the transmitting frequency.
- The frequency range is 76-108MHz.
- The frequency step can be 0.1MHz or 1MHz. Select a clear frequency that is not currently in use by local radio stations to avoid interference.

- Adjust Transmitting Power:
- The transmitter offers 11 power levels, from P01 (10mW) to P10 (500mW).
- Refer to the display for the current power setting.
- Higher power settings increase transmission range but may also increase interference with other devices or consume more power. Adjust as needed for your environment.
- Tune FM Receiver: Tune your FM radio (car radio, home stereo, portable radio) to the exact frequency displayed on the transmitter's LCD screen.
- Play Audio: Start playing audio from your connected source. The audio will now be broadcast through your FM receiver.
