Find the two green dots on the QUAL and +/- buttons on the left and right of the top of the camera. Hold them both down for a few seconds. The top LCD blinks and everything is back to normal
Which other settings are you trying to reset? Can you not just go to the custom settings menu and reset there?
Does it not tell you how to do it in the manual?
I still don't understand what you are trying to reset that you can't reset from the menus? For them not to be at factory settings then they must have been set via the menus by the previous owner, no.
Once reset, surely you will be going through the custom settings and setup menus to set them as you want them anyway, so why not just run down through the menus anyway and change what you want to change?
Maybe I'm just easily confused :shrug:
After much searching around, I really think you can't do this in the menus...
I have found them listed though, if it's any use to you.
