I swear I used to know how to do this with my Pro 2096,but when I want to temporary lockout a talkgroup I don't want to listen to I get the Memory Full error(I had just updated the scanner with new stuff since I hadn't updated it in years-I mainly use my Pro-106). I use the Pro 2096 in the basement when I'm in there doing stuff and my Pro 106 upstairs for every day listening.. Any help in refreshing my memory on this?
