just replaced new battery in my scantronic 9827 can anyone tell me how to r?

Jason, firstly did you ensure you put the red connector onto the red terminal and black to black. OK ensure the lid is on correctly, go to your keypad, enter your four digit code and then press tick.
Out of curiousity did you have BF come up in the display before the problems happened.
