Hi guys. I have here a 6510 unit with keypad malfunction problem. I already tried flashing the unit but it did not work. Then I check the continuity of nos. 4, 5,6, arrow up and call interface but I think its circuit problem. Can anyone please send me a schematic diagram for keypad interface.
Thanks a lot for your support. Sorry for my english.

i think that you need to change a small IC color yellow on the back of the board
