All or Some of the Keys on Console Will not Work
Possible causes:

If keys are pressed and there is a corresponding beep but the console does not
respond, then the upper board is likely defective.
•
Keypad connecting plug (N02 or N03) is not fit-in properly into the upper
control board. Verify the keypad connection.
•
The upper control board is not configured properly. Reference upper board
configuration in the table of contents.
