To work with appointments, select Appointments , or from a service call, select the Appointments tab.
The Appointment icon from the home navigation displays a notification number that indicates the count of new appointments after syncing your device. The notifications remain until the technician selects Dismiss New Appointments located at the top of the Appointments List (by selecting Appointments from the home navigation or from the Service Call > Appointments tab) or they sync the device again. If the technician selects Dismiss New Appointments from the service call, only the notifications for the new appointments related to the service call are dismissed.
You can select a view from the drop-down field to limit the appointments that display. The default view is All Appointments.
