How do timeouts work?

Under World Aquatics rules (Part Six, Article 5):

• Each team gets two timeouts per match, each one minute long.
• Only the team in possession may call one during play. During a stoppage, the team due to have the ball at the restart may call one. No timeouts during a video review or between periods.
• The Head Coach calls "Timeout" and makes a "T" sign with the hands to the officials' table or a referee.
• Players must move straight into the half they're defending. After 45 seconds a whistle lets players move anywhere.
• Play restarts with a free throw on or behind the halfway line to the team that had (or was due) the ball, or with the penalty throw if one had been awarded.

Invalid timeouts:

• Called by the team not in possession during play: a penalty throw to the other team, and the calling team loses one timeout if it has one left.
• Called by the team in possession with none left: a free throw to the other team on or behind halfway.
