Field Test

[Shamster]

Hey guys,
I was just messing around with my 3G Field Test, just looking around, and now I have this negative number on the top left corner, I'm pretty sure its the -db reading for the reception, but my question is how to get rid of it.

I restored, but its still there.

Thanks!
