How can I set Operating Hours for each display?
Go to Account > Tools > Operating Hours. Choose which display you'd like to configure. Under "Automatic turn ON", choose the time you'd like the display to turn on for each day of the week. Under "Automatic turn OFF", choose the time you'd like the display to turn off for each day of the week. If you don't want your display to turn on at all on a certain day of the week, leave the times for that day blank. Click the green "Save" button at the bottom when you're finished. Repeat for each player you'd like to configure.
If you want your display to be on every day, 24/7, click "Enable 24/7".
