Wireless: Do the Two Channel Tempest (CP-222 beltpacks) work with the Four Channel Tempest Base CM-242?
Tempest two channel BeltStations CP-222 now work with four channel BaseStations CM-242.Using the version 01.01.00 or later 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.
Note: Four channel BeltStations do NOT work on the two basestation
