+
+**NOTE 1:** Any changes performed in the editor will be overwritten when the associated alarm configuration XML file is
+imported again.
+
+**NOTE 2:** An alarm configured as enabled cannot be disabled using the checkbox in the editor dialog. Instead, user needs to
+specify a date/time when the alarm item is put back automatically into enabled state. At the specified date/time the alarm will be enabled,
+even if configured to be *disabled* by default in the alarm configuration XML file. Further, an alarm configured
+to be *enabled* by default in the alarm configuration XML file will be enabled when the file is imported, even if
+the alarm has been disabled in the editor by setting a date/time in the future.
