Nothing Seems to Work!
1• Verify if keypad is correctly
connected to the board.
If you are getting good voltage readings, but nothing seems to work,
carry out the following tests to correct the problem:
3• If nothing works, clean transformer
orange connector pins. Even a
small coating of film may cause a
bad connection.
4• Replace transformer if problem
persists.
5• If problem is still not solved,
replace board. (Refer to "How
to Replace the Board" section.)
2• Replace transformer fuse
if nothing still seems to work.
