When using certain sports helmets, and while driving at speeds above 70 mph, the Intercom connection may be accidentally activated. If you prefer, to avoid this from happening you may disable the Voice Connect feature (VOX). To disable Voice Connect, press and hold the Volume Up and Down Buttons simultaneously until you hear a beep. NOTE: The Enable/Disable Voice Connect feature affects only the Intercom. You will still be able to answer calls by Voice if you disable the Voice Connect (VOX) feature. Once Voice Connect is disabled, you may use the MC button, single press or double press, to establish/end Intercom calls with your Primary or Secondary buddy, respectively.
