4.15 NOISE CANCELLATION
XL Mobile radios feature Harris’ proprietary noise suppression capability to provide clear and crisp voice
quality in high-noise environments. This can be used in any mode, including analog and digital
communications.
The standard mic has two microphones; one located at the top (voice) and one on the bottom (noise
reference) (see Figure 4-6 and Figure 4-7). When noise cancellation is enabled, voice is picked up by the
upper microphone, and noise is picked up from the bottom microphone.
In the case where noise cancellation is enabled and the bottom (noise reference) microphone is blocked, the
radio operates as though noise cancellation is turned off.
4.15.1 Enable Noise Cancellation
To enable Noise Cancellation:
1. Press the Menu button to access the menu.
2. Navigate to the UTILITY menu.
3. Scroll up or down to highlight AUDIO SETTINGS and press the Group/Channel Select Knob.
4. Highlight NOISE CANCELLATION. Toggle Noise Cancellation ENABLED/DISABLED using the
Group/Channel Select Knob.
Refer to Section 5.6 for more information on the Audio Settings menu.
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.
