I haven't used my Bellsouth model 1008 two way radios for a long time....I just replace the batteries and turned them on but they are not in sink with eachother. How do I get them to transmit and receive with each other?

Sanity check. Make sure the radios are on the same channel. They shouldn't have to be "sync'd" The channel freqs are all hard set and can't be changed to my knowledge.
