Service manual
If your scoreboard contains two lines of display (two module system), the
top module mates to the bottom module via interconnect cable.
Note: On the connector itself, one guide is larger than the other
three. Align the guides on one end of the connector to the appropri-
ate slots on the other connector. Do not force the connectors
together. After slipping together, twist the securing ring to lock.
The securing ring will only lock if the proper connection between
the two interconnect cables has been made. You may have to access
the interior of the scoreboard module to loosen the white plastic
strain relief to add extra length for the interconnect cable.
Each end of the interconnect cable has quick connectors which lock
together.
Switches 1-4 on the #2860 control board and switches 1-6 on the #4290
control board are already pre-set at the factory for your particular sport
requirements.
For #2860 type control boards, the red selector switch, located on the con-
trol board, has 5 switches. The #4290 type has 7 switches. To set the
switch for the sports tunes, use the tip of a pen or a paper clip. Set the
switch before the electrical power is applied to either scoreboard, see Fig.
29 or 30, page 5-1 or 5-2, depending on the type of scoreboard you have.
Note: Once electrical power has been applied to the scoreboard,
you must first remove or disconnect power, then change the switch
setting, and finally reapply power.
Switch #5 (scoreboard #2860) or switch #7 (#4290) permits the choice of
allowing or disallowing the preprogrammed computer-generated sports
tunes to be played from the operator’s console through the speaker
system. The sports tunes include “Charge,” “Take Me Out to the Ball
Game,” “Taps,” etc.
To enable the sports tunes, the last switch should be “closed.”
To disable the sports tunes, the last switch should be “open.”
