    1. If shot clock is clear or two-sided transparent, reference proper switch settings with KB:  DD3188016
    2. If shot clock has an internal relay board and 3-pin XLR on the side; verify relay board set for:  (Relay card can be found with label 0P-1150-0242)

  2. For High Schools and younger leagues, Daktronics recommends you check with your state rules committee to ensure compliance before modifying these settings.
    1. Proceed only if for High School or younger league and you have checked with your state/league rules committee or rule book.
    2. Light strips are designed to act as EOP indicators (game clock=0) and are not factory set to light when shot clock=0.  However, if using Daktronics Shot Clocks or Light Strip Controllers with a All Sport control console they can be set to light at shot clock=0.  To change the settings for EOP's to light at both shot and game clock=0 do the following:
      1. Power down the shot clock at the breaker or power cord.
      2. Access the relay board in the shot clock.
      3. Set dip switches 2,4,6,8 to "On" to act as EOP as well as shot clock=0.
