4.15.2 Using Noise Cancellation
When using the noise cancellation feature, observe the following:
Verify NOISE CANCELLATION is enabled (see Section 4.15.1).
Talk within two (2) inches of the voice microphone.
Ensure the voice and noise reference microphones are not covered. See Section 4.15.4 for more
information on the voice and noise reference microphones.
Speak clearly, loudly, and with authority.
If necessary, it is o.k. to yell into the radio. The radio can handle loud input levels.
4.15.3 The Effect of Distance from the Microphone
Unlike a normal microphone system, noise cancellation makes the level of your voice diminish quickly as
you move away from the radio. The radio starts to see your voice as surrounding noise. Therefore, noise
cancellation requires that you hold the mic close.
