1.28 How to Undo/Redo Operations
The system stores the last 20 operations in temporary memory. This allows you to "un-
do" a mistaken operation, or several mistaken operations, at any time. You can also
"redo" an operation which was undone.
Note 1: The undo and redo functions are not available with the following items.
• Operation done before the power is turned off.
• Operation from the TX/RX menu (see section 4.7.2).
Note 2: When recorded echo data is played back, all the history contents of the can-
cellation and redo of the operation performed before the playback are erased.
