Bc2000 (for the BCF2000 & BCR2000)

hi everyone, i'm a new bcr2000 user and am experiencing problems that i hope don't mean 
my controller is defective.
it always occurs on the 6th row, so the 6th vpot and the 2 push buttons below it. when i use 
them, they send random actions. for example, i push the top button, but the 1st button is 
activated, re any other button except the one i pushed! same thing happens with the vpot. is 
my bcr defective? is there something i'm overlooking?? really confusing! 
also, the bottom right group of 4 buttons, one of those when pushed is even weirder:  it 
activates the panic reset or EG modes(which should only happen if pressing the 
store/edit/exit etc buttons).
can anyone help?  thanks, darren.
