2.1 Specifications
The table below shows all of the mechanical specifications, circuit specifications, and
maximum power requirements for each model in this manual.
* These are non-backlit displays. Power requirements are for convenience outlets only.
Notes:
1. Power shown includes max load placed on table including convenience outlets. Refer
to Drawing A-210619 for details.
2. Table counter top capacity is rated at 150 lbs max.
2.2 Setup
To set up a scorer‟s table:
1. Move the scorer‟s table to the desired location.
If more than one scorer‟s table is to be used as part of a
single display face, line the tables up side by side and
use the three metal latches (one above the counter top,
one next to the rear castors, and one on the lower-front
of the frame) to link the tables together.
The tension of the latches used to connect multiple
scorer‟s tables is not set at the factory. When engaged,
the latches should create a snug fit. If there is a
noticeable gap between tables, or it is difficult to clasp
the latches shut, the tension can be adjusted as follows:
a. Use a 5/16" wrench to loosen the nut that is
holding the metal hook in place.

b. Turn the metal hook clockwise to give the latch a tighter fit, or turn the metal hook
counterclockwise to give the latch a looser fit.
c. Make sure the metal hook is pointing downward and then tighten the nut.
2. Lift the table surface approximately 90 degrees and swing the side legs out and into place
underneath. Use the locking slots to secure.
Note: It may be helpful to have two people perform this procedure: one to lift and hold
the table surface and another to position and lock the legs in place.
3. Press down on the leg stops to make sure the table is level on both sides. For further
stability, also lock the rear table wheels.
4. For backlit models (and non-backlit models using convenience outlets), connect the twist
lock power cord to the power-in plug in the lower-right corner of the scorer‟s table, and
then connect the three pin plug to a grounding-type power outlet.

Maintenance & Troubleshooting 5
Section 3: Maintenance & Troubleshooting
IMPORTANT NOTES:
1. Always disconnect power before doing any repair/maintenance work on the display.
2. Permit only qualified service personnel to access internal display electronics.
3. Disconnect power when not using the display.
3.1 Display Information
Daktronics backlit scorer‟s tables occasionally require replacement of failed lamps or ballasts.
Refer to Drawings B-381209 and B-381575 in Appendix A for detailed wiring schematics and
refer to Section 3.6 for replacement part numbers.
Do not use higher power lamps or damage to the circuit may result.
Obtain replacement lamps and ballasts from Daktronics or a local store.
3.2 Display Access
1. Lift an end pad off one side of
the scorer‟s table and set aside.
2. Carefully slide the face panel out
of the retainer frame to expose
the internal components.
Refer to Figure 5.
Note: When multiple tables are
linked together, the metal latches
must be disconnected and the tables
separated before the face panel can
be removed.
3.3 Lamp Replacement
Lamps are held by “tombstone “-style fluorescent lamp sockets on each end. One socket for
each lamp will be spring-loaded.
1. Access the display components as described in Section 3.2.
2. To replace a lamp, grasp and push the lamp towards the spring-loaded end of the lamp
holder, then pull it out.
3. Replace lamps per the replacement parts list (refer to Section 3.6). Lamp sizes are given
in inches, stamped on one end of the bulb. The size is indicated by the set of numbers
following the letter “F.”
4. Close the display and reconnect power.

6 Maintenance & Troubleshooting
3.4 Ballast Replacement
1. Access the display as described in Section 3.2.
2. Remove every lamp from the display as described in Section 3.3 and carefully set aside.
3. Loosen the screw securing the 2nd access door from the left and lift it off the keyhole to
reveal the ballast.
4. Secure the wires on the ballast side of the wire-nut connections so the same color code
can be followed for the replacement ballast.
5. Remove the four (4) machine screw nuts securing the ballast to the display.
Note: The four screws holding the ballast are stud-mounted and will remain in place
after the ballast is removed.
6. Lift the ballast off the mounting screws and out of the display.
Note: Between each ballast and the display shell is an aluminum heat-sink bar. This bar
must be used with the replacement ballast.
7. Secure the replacement ballast and heat-sink bar to the inside of display using the four (4)
machine screw nuts previously removed.
8. Following the wire chart on the ballast, and using the color code of the existing wires
from the previous ballast (from Step 4), use the wire-nuts to connect the wires from the
lamps to the ballast wires. Call Daktronics customer service before continuing if there is
an inconsistency.
9. Slide the access door into place and reinstall the lamps.
10. Perform “Hy-Pot” and continuity tests to the display before activating power to ensure
all the wiring is correct and there are no shorts in the circuit.
