4. Operating Instructions
4.1 Wearing the Transmitter
Clip the mini transmitter(s) onto your clothing, ideally near your mouth, such as on a lapel or collar. The compact 8g size ensures comfortable wear and does not easily fall off.
4.2 Noise Reduction Function
To activate or adjust the noise reduction mode, double-click the volume button on the transmitter. There are 3 levels of noise reduction effect that can be adjusted to suit your environment, automatically filtering ambient noise for clearer audio.
4.3 Real-time Audio Monitoring
To monitor the audio being recorded, connect a 3.5mm earphone to the receiver's dedicated monitoring port. Click the volume button on the receiver to turn on the monitoring function. This allows you to check the sound effect in real-time without unplugging the receiver from your recording device.
