Some months ago it was posted on the forum how to do the Master Reset. If I am not mistaken White's requested it be removed and it disappeared from the forum. Recently I was not able to use the Expert Menu, I was getting "NOT RESPONDING" each time I tried to use it. I finally remembered that I had downloaded the instructions on how to use the Master Reset. I tried it and it worked to fix my problem. Now I am wondering why it was thought necessary to remove it. I would think it should have been included in the V3i manual.
