Operating procedures on each panel are described below.

stored data. If a data item is deleted, item numbers of data that follow it will be
decreased by one.
• Data Display after Deletion
If a data item is deleted, the data item after it is displayed. If there is no data after the
deleted data item (i.e., it was the last stored data item), the data item before the deleted
data item is displayed.

When data item 011 is deleted
Item 012 is deleted,
