Two-Way Universal Intercom; Three-Way Universal Intercom - Sena SF Series User Manual

11.2 Two-way Universal Intercom

You can initiate the Universal Intercom connection with non-Sena
Bluetooth headsets using the same intercom connection method as
you would between other Sena headsets. You may single tap the
Center Button to begin an intercom conversation with the first intercom
friend, double tap with the second intercom friend, and triple tap with
the third intercom friend.
Non-Sena Bluetooth headsets may initiate the Universal Intercom
connection, by activating the voice dialer or using the redialing
operation. You may also disconnect the existing connection by using
the operation to end a call (refer to the User's Manual for the headsets
for voice dialer, redialing, and ending a call).
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.
1. You (A) need to be paired with a non-Sena Bluetooth headset

intercom.
