ENABLING 3D AUDIO
Press and hold the PILOT Key to toggle 3D audio processing on and off
for all headset positions. When 3D Audio is enabled, the aural message
“3D audio left” is heard in the left ear followed by “3D audio right” in the
right ear. If the aural messages are not heard in only the left and then the
