Essentially a Business Unit groups devices together to allow users to be assigned to the devices they are responsible for. Locations are optional and for use in large organizations spanning across multiple buildings or when devices are located in different geographic areas.
If your organization has areas that specific staff is responsible for, a Business Unit is commonly created for each area. This structure allows you to manage who has access to devices and data based on their job responsibilities by assigning users to Business Units. By default, all devices are assigned to the account Business Unit.
Go to Devices > Clocks.
If you have multiple devices to update, be sure to use the multi-edit option. From the list, select all devices to update and from the bottom section select Edit Selected.
Select the Name link of the clock. Its profile is displayed.
Select Show Advanced Options.
From the Business Unit or Location setting, select an option from the drop-down menu.
