Start Multi-way Intercom
You can have multi-way intercom with up to seven other 20S EVO users by creating an intercom chain. Both the head and the tail of the chain can add new participants.
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 eight people.
Please note that each participant’s intercom friends are the ones adjacent to each other.
To have multi-way intercom with more than four participants, you must enable Eight-way Intercom.
