Ground Balance?

[jspoon]

Just got my CoRe today and have been playing around with it at the park. I can't get the 2 numbers to line up, I tried manual GB, if say my ground mineral is 66 I can't match it. Also when bobing the coil up and down and scroll the up-down button the tone doesn't change for pos or neg ground. What am I doing wrong? I'm use to the simplicity of whites machines.
I also read where Monte says he likes the machine because it remembers your settings, when I turn it off and back on I have to reset everything, was he tallking about switching modes without turning the machine off?
Thanks all!

Read the manual again.

I just watched the CD which I should have done before posting. What through me off was I was using the + - button instead of the up/dn button but this brings up another question, in the video to silence the hum he was pushing the up and dn button and bringing the hum down, then he reached over and started poking the + - button but the + - changes in increments of 10, well he was doing a fine job with the up dn button so why did he go over and start poking the + - buttons?
Sorry if I sound like an idiot but I'm dying to know..Thx
