Reset Wouxon KG-UV9PX Frequencies

When I received the radio, it had about 800 frequencies already programmed, but I made the mistake of saving it after I had done some tweaking, which all but eliminated them.

Is there a way to reset the phone to the default settings to restore them, or anyplace to reload them (purchased from Better Safe Radio)? I tried the reset in the menu, but it only restored 32 of the first frequencies.
