And see, I don't even understand what that means, but I don't figure it matters all that much since the CD469 seems to work just fine. I think if you can get significant results from even tapping a battery, I don't know what there is to worried about. Also, when the battery gets as low as 5 Volts, it seems to work just fine too. (I've had funny experiances when the battery was as dead as 2 volts though!)
Good night! (I'm going to a grand dinner with some very sweet old folks so I'm really excited! :) )
