Some sports do not enable shot clock functions.

If necessary:

Step 3 – Verify Shot Clock Power

Confirm the shot clock display has power.

If the display is completely blank:

  • Verify incoming power.
  • Verify the breaker supplying the shot clock is ON.
  • Restore power if necessary.

Step 4 – Verify Communication

If the shot clock has power but does not respond:

  • Inspect communication cables between the scoreboard and shot clock.
  • If using wireless communication, verify the receiver has power and is connected.
  • Confirm all connectors are securely attached.

Step 5 – Test Shot Clock Functions

Verify the following functions:
