NOTE
4.16 NOISE CANCELLATION
XL Mobile radios feature L3Harris' 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 4-7 and Figure 4-8). When noise cancellation is enabled, voice is
picked up by the upper microphone, and noise is picked up from the bottom microphone.
If noise cancellation is enabled and the bottom (noise reference) microphone is blocked, the radio
operates as though noise cancellation is turned off.

A button on the control head or KMM can be used to toggle profiles. See Section
