How does the shot clock operator start, stop and reset the shot clock?

Start or restart when:

• a team gains control of a live ball on the court (a mere touch by an opponent does not start a new period if the same team stays in control), or
• on a throw-in, the ball touches or is legally touched by a player on the court.

Stop but do not reset (remaining time stays visible) when the same team that had control is awarded a throw-in because of the ball going out-of-bounds, an injured player of that team, a technical foul by that team, a jump ball situation (not a ball lodged between ring and backboard), a double foul, or cancellation of equal penalties. Also stop without resetting when that team gets a frontcourt throw-in as a result of a foul or violation and 14 or more seconds are showing.

Stop and reset to 24 seconds (no display) when:

• the ball legally enters the basket,
• the ball touches the opponents' ring and is then controlled by the team that was not in control before,
• a team is awarded a backcourt throw-in (for example after a foul or violation, other than an out-of-bounds violation), or
• a team is awarded free throw(s).

Stop and reset to 14 seconds (14 showing) when the same team is awarded a frontcourt throw-in with 13 seconds or less showing (foul or violation other than out-of-bounds), or when the team that did not have control is awarded a frontcourt throw-in after a personal foul or a violation (including an out-of-bounds violation) or a jump ball situation. A team awarded a frontcourt throw-in from the throw-in line after a disruptive, flagrant or disqualifying foul also gets 14 seconds.

If the shot clock signal sounds while a team is in control of the ball, the timer stops the game clock.
