Four-way Intercom

Starting Four-way Intercom

You can have four-way conference intercom with three other 10Upad users by adding one more intercom participant to the three-way intercom. While you are having a three-way intercom, a new participant (D), who is an intercom friend of your intercom friend (C), may join the conference intercom by making an intercom call to your intercom friend (C). Please note that in this case, the new participant (D) is an intercom
friend of (C), not of you (A).

Ending Four-way Intercom

As is the case for a three-way intercom, you can completely get out of the four-way conference intercom or just disconnect a single intercom connection.

1. Press the Center Button for 1 second until you hear a beep to terminate a 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 Center 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 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).


Multiple headsets are connected during multi-way intercom. With various signals interfering each other, the intercom distance of multi-way intercom is somewhat shorter than that of two-way intercom.
