2. Use the Up (▲) and Down (▼) buttons to adjust the frequency. The frequency step is 100 KHz.
3. Select a clear FM frequency that is not currently in use by a local radio station to avoid interference and ensure optimal sound quality.
4. Tune your FM radio receiver to the same frequency displayed on the transmitter's LCD.

6.3. Adjusting Audio Input Volume

Rotate the Audio -VOL+ knob to adjust the input volume level from your audio source. Adjust this to prevent distortion (too high) or weak signal (too low). Aim for a strong, clear signal without clipping.

6.4. Adjusting Microphone Volume

If a microphone is connected, rotate the MIC. -VOL+ knob to adjust the microphone input volume.

6.5. Selecting Power Level (0.5W / 0.1W)

The transmitter supports two power output levels: 0.5W and 0.1W. The method to switch between these modes is typically indicated in the device's specific firmware or through a dedicated button. Consult the device's on-screen menu or a specific button combination if available. Higher power (0.5W) provides a longer transmission range, while lower power (0.1W) is suitable for shorter distances and may reduce interference in crowded RF environments.
