Priority Bed exit

Having an issue with the bed exit system. When using the nurse call on the siderail the bed exit triggers at the same time. I have replaced the ribbon cable off the board, replaced the 9v nurse call battery. Changed the communications cord, and gone through all the dipswitches on the board. When I hook it up to the curbell tester it gives me a P2 nurse call code for the side rail and the bed exit. I was wondering if there was a way to change the priority on the bed exit without having to have a tech come and redo the software configuration on it.
