Can't access Menu (or anything else) on keypad
My keypad lights up and makes a tone when I press the buttons and I put in my PIN, but as many times as I try I can never bring up the menu on the keypad -- it just goes back to displaying the mode. I also can't change btw Off - Home - Away mode or arm/disarm the system. I tried the battery trick, resetting the base station and... NADA. Help, please....
