Answer: For the lunch hour, from within Scheduler:
Click Block Time
Click the "New" button
Set your Color (other than white or black)
Select your date range
Select occurrence (Weekly)
Select your Days of Week
Set your Time of Day
Select yourself from the list of doctors on the right
Click Save
Problem: I created Blocked Time and it won't show on my schedule. I have checked my dates, the days, color of blocked time (made sure it's not white), selected doctor and schedule.
Solution: Reindex Scheduler
Ensure provider schedule extends beyond the blocked date
Ensure color of blocked time is not white
