OK GUYS, I had a similar problem with an R8 that I had, and that's one reason that I "HAD" it, and now don't, but anyway. This is the unofficial Art Tafil way to fix it that I found worked, at least for me, "Smack It" good and hard, on the base with the palm of your hand. This probably seated the contacts better. Of course I also threatened to trade it even for a Petri 7S, 1.8, and that always seemed to work. No Kidding!! Of course you guys have to realize that I'm pretty much certifiable! Art Tafil
