Which type of Equipment Management (EM) inbox message must be deleted manually by the user?

The reason the advisory notice is the type of Equipment Management inbox message that must be deleted manually by the user is tied to its purpose and nature within the management framework. Advisory notices are generally informational in nature and are used to provide users with guidance or updates that do not require immediate action or response. Unlike more urgent messages, such as action required or urgent alerts that demand prompt user attention and resolution, advisory notices remain active in the inbox until the user decides to remove them.

In contrast, action required messages typically involve a direct task that must be completed by the user, while urgent alerts often indicate critical situations that require immediate intervention. Informational updates may contain useful data but are not necessarily time-sensitive. Thus, the advisory notice's characteristic of being informational without an urgency directive necessitates that the user actively manage it by deleting it when they choose, highlighting its unique operational role within the Equipment Management system.
