Install New v6 Main PCB

Smith's Medical Medfusion 4000 - After replacing the Main PCB, with the pump powered off, I press and hold the Decimal and Power buttons to initiate the software configuration install from the Interconnect PCB but, it never takes. Am I doing something wrong? Am I supposed to allow the pump to alarm for 5 minutes or something? According to the manual, you power off after you get the alarm but, my pump alarms immediately after starting the update . Also, how do I get the new Main PCB to register the battery? The new board literally detects no battery stats at all. Thanks.
