Firing Systems: 1200 cue "Import" Firing System, pairing and other tricks, 4K

OK, I have shot various videos about these "import" firing systems but this one is with posting, it is the basics you need to l know to set up your console to work with the remote firing units regardless of how it is paired or for you expand your system with new remote firing units since I doubt anyone buys 100 sets at once. Did not need to be in 4K, I just forgot to change the settings. PS - I hate this carpet.
