My 6600 phone keypad won't work??what should i do??i evenly change my housing?? actually the 456 button are the key that doesnt work,, please help me,,


The inner terminals of 4,5,6 and call (green) buttons are the same or common. If this line is cut or open these buttons will not work at all.
  • If the call (green) button works but the other three buttons do not work, just connect a thin jumper wire from the inner terminal of the call (green) button to any of the inner terminals of the 4,5, and 6 buttons.af1ea52.jpg
  • If the four buttons do not work, make a thin jumper wire from any of their inner terminals to the terminal 4 of the keypad connector as show in the picture below.e65d98b.jpg
