The Tone Key is an inaudible fre-
quency that is transmitted along
with the audio signal. It assists in
reducing audio interference from
other RF devices. When trouble-
shooting audio issues, it may be
helpful to turn the tone key off.
For best performance, it is recom-
mended to always have the Tone
Key activated.
