Landmark Microprocessor Chip (Version F10) is required for the CID-6 Caller ID Unit to work. Depending on when your KSU was manufactured, you may have Version F08 or older which are not compatible with the CID-6. On the main circuit board, look at U9.....if your microprocessor is less than F10 you will require this part.
