3. Procedure for programming an MCU prior to installation at door.
Note: LCU is not connected or utilized in the advance programming of the MCU. If the
LCU is connected to the MCU during this process the two components will register to
each other and require the installer to keep the MCU and LCU together as a matched
pair until installed onto the door.
