1.2 Identification
ALL-AMERICAN uses a 5 digit serial number for scoreboard identification. The
serial number tags are located on the back of the control console and the lower right
hand corner on the face of the scoreboard display. When contacting the factory for
assistance it is important that the model number and serial number are known.
1.3 Damage
Upon receipt, check for visible damage. If this occurs, or if damage is found after
shipment has been accepted, follow the damage claim procedure.
1.4 Damage Claim Procedure
An instruction sheet is enclosed advising the consignee in case of damage in transit.
If damage is noted at the time of delivery, consignee must obtain an 'Inspection of
Bad Order' from the delivering carrier. In order to process your claim, this must be
properly filled out with a complete statement of all damage and it must be signed by
the carrier.

If damage is discovered after delivery, you should call the delivery company. Have
them make out a Concealed Damage Report. Fifteen days after delivery are allowed,
so this should be done promptly or it is impossible to process this claim.
Advise EVERBRITE corporation of necessary replacement parts, or repairs.
Consignee will be invoiced and then should file a claim with the carrier to recover
charges. To file your claim follow this procedure:
(A) Cost of replacement parts or repair charges are invoiced to the carrier by the
consignee.
(B) The following documents, properly filled out, plus invoice, are
forwarded to the trucking company in support of your claim:
(a) Original bill of lading
(b) Original paid freight bill
(c) Certified copy of original invoice
(d) Standard form for presentation of loss and damage claim
2. INSTALLATION
2.1 General Information
Shipping papers accompany each scoreboard. Check carefully to see that you receive
the following:
2 ea Scoreboard Displays
1 ea Control Console
1 ea Service Manual
1 ea Mounting Hardware Package
? St Control Cable (if ordered)
IMPORTANT!
The MP-40 cable supplied by ALL AMERICAN SCOREBOARDS for use on the
Microprocessor based scoreboards is specifically designed for this system. Use of
a substitute cable may void the warranty on the scoreboard!
2.2 Inspection
Inspect each unit and tighten all screws, lamps, and fittings that may have loosened
in shipment.
2.3 Pre-Test
Before installing the scoreboard, pre-test all functions.

2.4 Installation
Select the location best suited for visibility by the majority of spectators. Preferred
position is facing east or north to avoid direct sunlight on the face of the scoreboard,
if day games are played.
The MP-40 direct burial data cable carries only low voltage signals and therefore can
be installed with or without conduit, consult section
6 for junction box and
scoreboard wiring.
2.5 Electrical connections
This scoreboard requires a 120
V. 60 HZ 2 wire with ground 20 AMP service for
the exclusive use of the scoreboard.
NOTE
To protect the MP-2002 control from damage, it is advisable that you disconnect the
control and store in a dry secure area when not in use.
NOTE
This equipment is ETL (Electronics Testing Laboratories) CSA and NRTL approved
and complies with the requirements in part
15 of the FCC rules for a class A
computing device. Operation of this equipment in a residential area may cause
unacceptable interference to radio and television reception, requiring the operator to
take whatever steps are necessary to correct the interference.

Push to alternately dim and broghten the lamps in the display.
4. MAINTENANCE AND TROUBLESHOOTING
4.1 Introduction
This section gives maintenance and troubleshooting information. Included are
troubleshooting guides for typical scoreboard malfunctions. If the cause of a problem
cannot be determined, please contact the customer service department.
4.2 Test Equipment
IMPORTANT
!!!
In this scoreboard the 120 volt line is on the lamp socket all the time, and the
common is switched to turn the lamps on and off. For this reason, to avoid
damage to the equipment or personal injury, it is important to turn the main
power off when changing the lamps.

A simple analog or digital voltmeter will be sufficient for all user repairable
problems. Printed circuit boards requiring troubleshooting should be returned to the
factory.
4.3 Troubleshooting
Whenever possible, follow the troubleshooting guides prior to contacting the
customer service department. If a problem not described in the guides exists, contact
the customer service department immediately. Refer to the diagrams provided for
assistance in troubleshooting scoreboard malfunctions.
4.4 Troubleshooting Guides
(A) Scoreboard doesn't light and console doesn't work
(a) Check that the main power switch is turned on.
(b) Replace any defective or blown fuses.
(c) Check the power connections and voltages at the scoreboard,
(d) Contact the customer service department.
(B) Scoreboard digits don't light, but the console works
(a) With the main power switch "off"; remove the cover over the controller
assembly.
(b) Check all connections.
(c) Turn the main power on.
(d) If the scoreboard still doesn't light, check the transformer voltage going to the
receiver PCB (printed circuit board) assembly (blue wires) using a voltmeter
set on the 12 VAC or higher scale.
If the voltage is less than 8 VAC contact the customer service department.
If the voltage is between 8-12 VAC see the replacement parts list for a
receiver PCB assembly, and contact the customer service department.

(C) The scoreboard digits light but the console doesn't work
(a) Check for continuity between the scoreboard and the junction box.
(b) If an open circuit is found, the problem is either the cable or a cable
connection.
(c) If the continuity test checks good, check the voltage between the green wire
and the white wire in the junction box, using
a voltmeter set on the 12 VAC
or higher scale.
If the voltage is
0 VAC see the controller parts list for a transformer
assembly.
If the voltage is less than
8 VAC consult the controller wiring diagram for
instructions on long cable compensation.
If the voltage is between
8 VAC and 12 VAC contact the customer service
department.
(D) The scoreboard digits light, the console works, but there is no control of the
scoreboard.
(a) Check the voltage between the black and red wires in the junction box with a
voltmeter set on the
3 VDC or higher scale. The voltage should read
somewhere between
2-3 VDC when the console is working properly.
(b) If the voltage is
0 VDC contact the customer service department for
assistance.
(c) If the voltage is correct,
(2-3 VDC) check that this reading also appears at the
scoreboard.
(d) If the correct voltage also appears at the scoreboard, see the replacement parts
list for a receiver PCB assembly.
(E) The scoreboard works, but some lights stay on all the time
(a) With the main power "OFF", switch the plug from the bad digit with the plug
for a known good digit.
EXAMPLE: Plug "A" into "B" and "B" into "A" locations,
(b) Turn the power back on. If the same lamps remain lit all the time, the
problem is a shorted lamp socket. If the lamps on a different digit now stay lit
all the time, the problem is on the driver PCB assembly. See the replacement
parts list for the proper replacement part.
(F) The scoreboard works, but some lights do not come on.
(a) Check for burned out lamps.
(b) Check for a broken wire or bad connection on the 12 pin connector.
(c) See the replacement parts list for the proper replacement driver board
