6.9 System Con guration Changes

An alarm message like the following appears when a system con guration change (or the
possibility of a con guration change) is detected.
If the system continues to operate after its con guration has changed, distribution ratios and other
data will be totally inaccurate. For this reason, cut-off processing must be done with the system
in the state before the change. The following message is displayed to ask you to con rm the
processing.
Operation procedure for each case is as follows.
