I used to own a Pro-64 (believe that was the number) and I could go to any ID I wanted to listen to and it would stay there untill I pushed scan. I believe I pushed HOLD and then entered the ID numner - exam: 1137 and it would lock on that ID. I now own a Pro-164 and I can not do that function. I do not see anything in the owners manuel and there is no HOLD button - just a pause button. Does anyone know if this can be done and if so how? It is real frustrating to have to wait for the Group ID to talk before I can lock it on so I don't miss anything in that ID - gets old to have to keep pushing scan to keep searching for that ID untill they talk and I can then push the pause.
