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.
