The Customize menu of the Menu Bar provides THREE functions that help you to define and edit filter criteria for the display of the alarm list or the alarm log: New Filter, Edit Filter and Delete Filter.
To delete an existing filter, you must have selected Active Alarms/Alarm Log or Active Events/Event Log in the Tree View in the left-hand section of the screen, and in the tree branch - the filter you wish to remove.
Procedure
Careful
The filter is deleted IMMEDIATELY and WITHOUT any further confirmation !
