Please note
:
- If you add a new iCAT definition, it will automatically be assigned to all iCAT schedules of the
camera. If you do not want that, you have to remove the assignment manually (see
15.3.15
Scheduling iCAT operation and recording
on page 160).
- If a definition is not assigned to a schedule then it will not be activated and no archive
recordings will be made and no events will be generated.
