The Calendar shows different pieces of information in a Work Order to indicate different requests or responses from the customer.
Each piece of information is designed to tell you at-a-glance something about the Work Order
The (1) or (2) on the calendar is the # of appointment reminders that have been sent, set from your Settings/Appointment Reminders page
Note If an appointment is moved after reminder has been sent, the (1) or (2) disappear from the appointment as the reminder is reset
AT: Any Time is the customer’s time preference set in the Edit Location page
CB: The appointment is a Callback as indicated in the bottom-right corner of the Work Order, No charge (Callback) [x]
Clock: Specific time window for the tech to show up, set from your Settings/Calendar page
Check mark: the Confirmed box in the Work Order - Schedule tab is check
Note If your appointments are too close together the symbols can get pushed out of the appointment. You can double the size of hours in the Calendar, that might allow for more room for the symbols.
Go to Settings/Calendar & Time and put a check mark in [x] Double Size Calendar. This will make the calendar twice as high, allowing for more precise scheduling, and allowing room for the symbols.
