To manually use ART on a zone, do the steps that follow:
NOTE: The system must be in RUN mode before the ART process can start.
1. On the ART Process screen, select the zone or zones on which the ART process will

2. Touch the Start ART Process button to start the ART analysis on the selected zone(s).
As each zone completes the ART process, a green checkmark shows for that zone.
To cancel the ART process during its operation, touch the Cancel ART Process button.
