6.4.2 End Four-way Intercom
As in the case of three-way intercom, you can completely exit from the
four-way conference intercom or just disconnect a single intercom
connection.
1. Press and hold the Center Button for 1 second until you hear a
beep to terminate four-way conference intercom. It terminates the
intercom connections between you (A), and your intercom friends
(B) and (C).
2. Tap or tap twice the Center Button to disconnect the intercom
connection with one of the two intercom friends accordingly.
However, when you disconnect the second friend (C) by tapping
twice the Center Button, you will be disconnected with the third
participant (D) as well. This is because the third participant (D) is
connected with you via the second friend (C).

6.5 Intercom Failure
When you try to start an intercom conversation with an intercom friend
who is already having a conference intercom with other riders or is on
a mobile phone call, you will hear a low tone double beep signifying
that the intercom is busy. In this case, you have to try again later.
6.6 Intercom Reconnection
If your intercom friend goes out of range while having an intercom
conversation, you may hear static and eventually the intercom will be
disconnected. In this case, the Sena Expand Boom automatically tries
to reconnect the intercom every 8 seconds and you will hear high tone
double beeps until the intercom is reestablished. If you don't want to
make a reconnection, tap the Center Button to stop the attempt.
