What must teams do following the coin toss for a deciding set?

After the coin toss for a deciding set, the proper procedure is for teams to switch benches upon the first referee's signal. This is important to ensure fairness, especially since teams may have different conditions on each side of the court, such as lighting or wind direction. Switching benches means that each team has the opportunity to experience the same conditions, which is vital in a deciding set where the stakes are highest.

In some cases, if a team is already familiar with one side of the court due to previously played sets, switching helps level the playing field. Coaches and players must be prepared to move quickly and follow the referee’s signal in order to maintain the flow of the game.
