Ok,let’s see if I can help you through the procedure. When you turn on just the transmitters are the frequency numbers in the display windows the same or different? If they are different then the matching receivers should be the same as it’s transmitter. Each set should have the same numbers but different from the other set. If they are different than you’re ahead of the game.
Go into the menu of each piece to set the sensitivity or RF output. Set the tx (transmitter)at -20 and the rx (receiver) at about the same. All is explained in the operating manual, just focus on one parameter at time. It’s alot easier to talk than type so if you’re really stuck call me and I’ll try to talk you through the setup procedure.
