How do you do a full factory reset on the X920BT? I don't mean the "Reset Factory Default Settings" that you can get to in the "Settings" menu--I mean an entire wipe-the-memory, restore the unit to the way it was when it left the factory reset.

Its in the manual.

Its in the manual.

but there is no "button combination"? I couldn't find one in the manual. Usually there is a hard-button combo to do a diagnostic reset of some kind. Do you know of one of those "un-documented" ones?

No but I do seem to remember some posting something like that in a thread the other day. Regardless there are reset proceeders posted in the manual.

I have the manual. ONLY if the unit is powered on, and you can see an image (at least as far as I could find).
