Operating Instructions
Noise Cancellation
The BY-V30 features a one-click noise cancellation function for crystal-clear sound. To activate or deactivate noise reduction, simply press the "NR" button on the transmitter. A static green light indicates noise reduction is enabled. If the microphone is muted, the blue light will blink slowly.
