If the 40-second clock does not start or the count is interrupted for reasons beyond the control of the officials or the play-clock operator (e.g., clock malfunction), the referee shall stop the game clock and signal (both palms open in an over-the-head pumping motion) that the play clock should be reset at 40 seconds and started immediately. 2. In the event that the 40-second clock is running and the ball is not ready to be snapped after 20 seconds into the count, the referee shall declare a timeout and signal that the play clock be set at 25 seconds. When play is to be resumed, the referee will give the ready-for-play signal and the play clock shall begin the 25-second count. The game clock will start on the snap unless it had been running when the referee declared a timeout: in that case, it will start on the referee's signal. .
