TESTING, OPERATION, AND ONGOING CARE
After all power, data, and other connections are in place, it is time to test the shot clock
system. Apply power to the shot clock displays first. Although there is no harm in
powering the control console first, powering the signs first should result in the numeric
displays to remaining blank. Seeing any LEDs illuminated on one of the shot clock
displays prior to the availability of data from the control console would indicate a
problem inside of the shot clock cabinet.
Next, power up the control console and plug in the three-button handheld shot clock
switch assembly. For wired setups, connect two stereo patch cables to data output
ports on the back of the control console. The other ends of these patch cables are
typically plugged into junction boxes, but may be plugged directly into the data input
ports on the tops of the displays for testing.
The shot clock displays should begin showing data within a few seconds. Use the
three-button handheld device to reset, blank, and restore the shot clock time. The
[SHOT CLOCKS] button on the control console should allow you to change the time
showing on the displays (while the Period Clock is not running). For more details about
how the control console and handheld switch assembly work, consult the
documentation that ships with them.
Scheduled Testing and Maintenance
The shot clock system does not require scheduled maintenance procedures. However,
it is important to check for problems prior to a game. We recommend running through
the tests described above between two and four weeks prior to the start of a season (or
anytime you plan to use the shot clocks after a gap of more than a month). During the
season, test out the shot clocks the day before each game.
After the Game, and After the Season
Whenever you are not using your shot clock system, use the disconnect switch(es) to
cut power to the signs. You should unplug the control console from its power source
and from the data cables as well. It is not necessary to take steps beyond this, even if
the shot clocks will not be used for several months.
