Vertex vx354 issue

I have taken over the Radio's at my Fire Dept. and the last company that programmed our radio's messed up our systems. ch.1 Fire F-1, Ch.2 Fire Page. when our dept. we use to be able to hear the call out after our radios went off when our tones was dropped. now we have to get to our radio's and switch from channel 2 Fire Page to Channel 1 Fire F-1 to be able to hear what our call is. Does anyone know how to fix this? I am kinda new with this programming software and don't want to be like our other guy and fry the radio's...



Thanks!
