NOTE

5.17 NOISE CANCELLATION

XL Series portable 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 radio has two microphones; one located at the top of the radio (primary) and one on the
bottom (secondary). When noise cancellation is enabled, voice is picked up by the upper left
microphone, and noise is picked up from the bottom microphone.
In the case where noise cancellation is enabled and a speaker microphone is attached to the
radio, talk into the speaker microphone. In this mode, the radio's top left microphone is used to
pick up the surrounding noise, and the other microphone is unused. See Section 5.17.4 for more
information. If the bottom (secondary) microphone is blocked, the radio operates as though noise
cancellation is turned off.
