Yeah, but the thing that gets me is that my radio always looses the
stations if I disconnect the cables for even 1 second. Sears did a good
fast job, but I don't think they could do a sub 1 second bat change...
I thought someone might know if they kept current going through the
cables as a customer convienance thing so you wouldn't have to reset the
clocks and everything.
