What circumstance allows for an official to use a designated timeout?

A designated timeout is typically used by the officials under specific circumstances to manage game situations effectively. In the context of addressing bench technical fouls, the official has the authority to call a designated timeout as a formal way to address any infractions committed by coaches or team personnel. This timeout allows the official to manage the situation, maintain control of the game, and provide the necessary communication regarding the technical foul.

In contrast, calling a designated timeout cannot be done simply at any player's request, nor during player substitutions, as these moments of gameplay have their protocols. While correcting the scoreboard is a critical function during a game, it does not warrant the use of a designated timeout in the same way that managing bench technical fouls does. Hence, the use of a designated timeout is appropriately aligned with the need for officials to handle specific disciplinary actions or game management issues on the bench.
