My experience with lockout problems
On a couple of occasions, I have accidentally locked out all the groups in a system on both my 396 and my 996. I was unable to unlock any of the groups and had to go through the painstaking and lengthy task of reprogramming the entire system. Because of the fact that I don't have my programming backed up in a computer so that I can simply upload (is that the right word?) the programming back into the radio, I have now made copies of all my systems within the radio itself. Now when this happens, I can simply go to one of my copies and get my system back. I erase the messed up system first, then I make another duplicate of the copy and my problem is solved. If you don't have your systems backed up in the radio like me, you will have to wait till you can get to a computer. I'm not good with computers but I'm an expert at doing it the old-fashioned way. Field programming is a snap for me. LiberaFan08
