  1. Did the firmware upgrade using the UCM Firmware cable complete?
  2. Remove the UCM Programming Cables from the Comfort PCB
  3. if yes, reset the Comfort by pressing the reset button in Comfort. That should start the operation again.
  4. If not, nothing will work includng the  keypads. what was the error message? Repeat the Firmware upgrade
