After requesting imported messages, you can see only those messages that have been added to the unit history using import. The same features are available for them as for data messages received from the unit. The only difference is that all rows in the table of imported messages are highlighted in light yellow, and dashes are shown in its Registration time column.

To delete messages that have been imported by mistake, select them in the last column and click on the icon  at the bottom of the table. To delete all messages in the table, select the checkbox in the heading of the last column and then click on the icon.
