For example, if you have a three-way intercom set up, the new
participant (D) can be added to either (B)-the head, or (C)-the tail. If
(D) were added to (C), then (D) becomes the new tail of the chain. If
(D) were added to (B), then (D) becomes the new head. In this way, an
intercom chain can hold up to a total of eight people.

You can completely get out of the multi-way intercom or just disconnect
a part of the chain.
1. Press the Center Button for 5 seconds until you hear double
beeps to terminate multi-way intercom. It terminates the intercom
connections between you (A), and all participants in the chain.
2. Single tap or double tap the Center Button to disconnect intercom
connection between one of the two intercom friends. A single tap
will disconnect the intercom connection between you (A) and (B).
Rest of the connection of the chain will be preserved. Likewise,

(A) and (C), while preserving rest of the connections.
