MICROPHONE NOISE CANCELLATION
Active Noise Cancellation (ANC) can be applied to the sound detected by the
microphone before transmitting it to other radios.
• When On, ANC works to ‘keep’ sounds with the characteristics of voice
but suppress sounds interpreted as background noise. This is most helpful
for keeping your voice understandable when you are in a loud or noisy
environment. However, ANC may suppress desired sounds if you want
receiving radios to hear other voices or sounds occurring around you.
• When Off, the radio will not suppress sounds detected by the microphone.
This is most helpful when transmitting in a quiet environment or when you
want receiving radios to hear other voices and sounds occurring around
you. However, the background sounds may make it harder to understand
what you are saying.
