Lcd Battery meter not responding?

I bought this battery meter a while back it turned up in the mail today, all the buttons are non responsive except the front button that turns the back light on and off. The lcd displays 0% some help would be greatly appreciated

pretty sure some of those jumpers numbered from F1-F5 need to be connected depending on the settings wanted

This may be of some help

Have you set it up to match the battery voltage your using?
