Reset Pro-668 to factory default settings

After customizing my 668 this weekend, I find that I've set something that prohibits my hearing all but a couple stations. I'd like to reset everything -- database, playlists, talk groups, sites -- so the 668 is configured just like it came out of the box new.



I've read every bit of information I could find here in the forum and searched the Internet, but I didn't recognize anything that would help.



Thanks in advance.
