You can go to www.futaba-rc.com and download just about any manual. Sometimes it helps to just reset to factory defaults and start over because a previous owner (or you) has gotten things so screwed up it will take forever to fix it. Or sometimes it's just one switch too.

Default is a lifesaver though.

BTW - if it is the 8UAFS, it is a nice unit . I have a 7UAFS.
