Sorry for the delay in getting back. Since the scan works on the side button I don't think I have an issue with my scan list. So I deleted the scan function from the side button, programmed the radio and disconnected it. Reconnected, read the radio and confirmed scan was not assigned to any of the buttons or switches. So I went back to the toggle switch settings and selected scan and I get the same error, conventional at the top of the list turns red and if I scroll over "scan" I get a circle with a line through it. My options for the toggle are, TA/direct, channel select, zone select, scan, unprogrammed, blank, pl disable, tx low power, scan list program and keypad lock. The first 4 items all show an error and won't let me program them to the toggle, only the last 6 items. As a side note I do not have an option listed on my display menu for scan, only program scan to select or unselect a channel from the scan list. I greatly appreciate all the replies. It's a real head scratcher, I figured out channel announcement and have it working but can't get something as simple as scan on the toggle switch.
