Tempest two channel BeltStations now work with four channel BaseStations.

Using the latest version of Tempest firmware, a two channel BeltStation can be paired and used with any four channel BaseStation. The two channel BeltStation operates on intercom channels A and B only. Channels C and D are unavailable to the two channel BeltStation.

Both two channel BeltStation modes are available so the two channel BeltStation can dual talk/listen on A and B, or it can switch back and forth between A or B depending on user preference. Using two channel belts is a great way to add flexibility.
