Bernie, The instructuions in the manual do work, just a little cryptic. The answer of "in the manual, suggest you read it" is of limited use, since I for one lost my manual in a flood. A link or how to find the manual is better is much more useful. You can get a copy of the manual going to the home page of Buffalo then to documentation. There you enter the model number and so forth...
It would help when you log in if the Buffalo people would have a list of Model number and not the name of the product. As I don't remember such things and I look on the back to guide me. If they had the name along with the model, it would be much better.
It seems like you have solved it via other paths, I just wanted to let you know I did do it via the manual instructions. I had to do it a couple of times as it isn't clear when you hold down the button and when you just press the button...
