Please note that in this case, the new participant (D) is an intercom friend of (C), not of you (A).
8.3.2 Ending Four-way Intercom
As same in the case of three-way intercom, you can completely get out of the four-way conference intercom or just
disconnect a single intercom connection.
1. Press the Front 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 double tap the Front Button to disconnect the intercom connection with one of the two intercom friends accordingly.
However, when you disconnect the second friend (C) by double tapping the Front 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).
Disconnect (B), (C) & (D)
