3. AF Indicators (AF): These lights
flash green when audio (voice)
from the microphone is detected.
4. A VOLUME: Controls the volume

will provide an adequate signal. It is not necessary to increase
the intensity of your voice—the amplification system provides
adequate amplification (approximately 5 – 10 dB) above
ambient room noises.
