Here's the main deal .... Turn them on, put them in public Mesh, ... DONE ... you are now talking to anyone else with a 30K, no buttons just talk. easy pessy ;-)
I suggest you watch ALL 6 30K videos on the RKA RU-vid page to fully understand all the functions. "When connected together in a private Mesh, the headset will automatically save the connection information from all of the other headsets that it has connected to for future Mesh intercom group communication". When Mesh intercom is enabled, the headset will be in Public Mode initially. It can connect with a virtually unlimited number of nearby 30K headsets within a 1.6 km (1.0 mile) range ..... No pairing or connecting is needed!
