When you edit your scan list to only the channels you need for that day then when i go to put them back it will have the scan list in that zone and other zones all screwed up.All i normally do to fix this is to put it on the computer at home and write the radio with a good code plug.Sometimes this is a problem if you don't have your PC to fix this with you when you are out of town.I have most of the zones so i don't have to edit the scan list.

1 why does this happen
2 can you fix this through the menu on the radio?
