Replace an MCU

When the system has more than one MCU, each MCU contains a

complete set of configuration information for the entire system. This

includes handset registration information, function definitions, and

frequency sequence selection.
This Configuration Sharing feature allows a failed MCU in a multi-

unit installation to be replaced without having to register the handsets

again.
To replace a failed MCU, first clear the configuration information on

the replacement MCU, then replace the failed MCU.
