How does the timer sound signals for time-outs and intervals?

The timer is provided with a game clock and a stopwatch, and measures playing time, time-outs and intervals of play.

Signals in general

• The game clock signal must sound very loudly and automatically at the end of a quarter or overtime. If it fails to sound or is not heard, use any means possible to tell the referees immediately.
• The timer sounds the signal only when the ball is dead and before it becomes live again. The signal does not itself stop the game clock or the game, or make the ball dead.

Time-outs

1. Start the stopwatch immediately when the referee blows the whistle and gives the time-out signal.
2. Sound the signal when 50 seconds have elapsed.
3. Sound the signal when the time-out has ended.

Intervals of play

1. Start the stopwatch immediately when the previous quarter or overtime has ended.
2. Notify the referees before the first and third quarter when 3 minutes and 1.5 minutes remain until the start of the quarter.
3. Sound the signal before the second and fourth quarter and each overtime when 30 seconds remain until the start.
4. Sound the signal and stop the stopwatch immediately when the interval has ended.
