Running the shot clock
- The shot clock runs only while the game clock runs, and resets automatically at the start of each period.
- Tap the full reset (24) on a change of possession and the short reset (14) after an offensive rebound. The S key does the short reset.
- When it reaches zero it sounds the buzzer and flashes, while the game clock keeps going until you stop it.
