2 Retrieving the latest echogram history
The History information pane allows you to view previously recorded echogram sequences.
Context
The History function saves the echogram images automatically on the hard disk These images can be recalled using the History information pane. The information in the History presentation is the same as on the original echogram presentation.
Note
The number of history files is limited. After reaching the maximum number of files, the latest echogram picture overwrites the oldest one. The history function still allows you to quickly look through echogram pictures from several hours.
Every time the history file is saved to the hard disk, the pinging may be interrupted. It is therefore possible to disable the History function. This function is located on the File Setup page in the Output dialog box.
