Hi all.

I can't seem to get my Fender LX-12 chromatic tuner to work. I connect a lead from my guitar to the 'IN' port of the tuner, turn it on, pluck a string and nothing happens. It's on auto mode and that comes up on the lcd display, but there's no indication of recognition when I pluck any of the strings. It also comes up with 'CENT' on the left side of the screen, if that's important.

Any help would be fantastic.
