11.3 Three-way Universal Intercom (SF4)
You may make a three-way Universal Intercom connection with two
SF4s and one non-Sena Bluetooth headset. If the intercom connection
is made, all headsets connected cannot use the mobile phone call
function since the connection between the headset and the phone is
disconnected temporarily. If you disconnect the intercom call, the
mobile phone connection is made again automatically so that you can
use a mobile phone call function.
