Now look @ where the frequencies are listed. You see those numbers that look like this 01, 02, 03, 04, etc.? Each frequency should have one right before the frequency itself. Those are the L.C.N.s.
Since this is a Multi-Site Trunked Radio System; each site will have its own set of L.C.N.s.
Program in all the frequencies for site or al lthe frequencies for different sites and yo ushould be good to go.
Unlike a Motorola Trunked Radio system; you will need to program in ALL the frequencies for each site and NOT just the Control frequencies! I am NOT sure what radio scanner you have but if it is an older one like the Pro-92B then you would need to program in each site in its OWN SEPERATE BANK.
