1. GENERAL INFORMATION
1.1 DESCRIPTION
Your All-American scoreboard has been carefully inspected and tested before leaving
the factory. It is possible, however, that components may
be loosened or forced out

S. Main Street
Pardeeville,
WI 53954
NOTE
If you need
to send parts in for repair, please call the ALL AMERICAN
service department for a returned goods authorization (RGA) number.
1.2 Identification
ALL-AMERICAN uses a
4 digit serial number for scoreboard identification. The
serial number tags are located on the back of the control console and the lower right
hand comer on the face of the scoreboard display. When contacting the factory for
assistance it is important that the model number and serial numbers 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 damageis 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:
1 ea Baseball Display
1 ea Control Console
1 ea ServiceManual
1 ea Mounting Hardware Package
1 ea Press Box Junction Box
? ft Control Cable (if ordered)
2.2 Inspection
Inspect each unit and tighten all screws, lamps, and fittings that may have loosened
in shipment.
2.3 Data Cable Installation
The MP-40 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.

2.4 Electrical connections
This scoreboard requires one 110
V. 15AMP AC circuit for the exclusive use of the
scoreboard.
3. CONTROL CONSOLE OPERATION
3.1 Scoreboard Power
Turn on the branch circuit(s) to the scoreboard(s). The scoreboard lamps will come
on in a random fashion.
3.2 Console Display
The Liquid Crystal Display module displays the scoreboard information entered from
the control console.
3.3 Console Power
Plug the control console cable into the Press Box junction box.
Push
Push
once to turn the console on.
a second time to shut the console off.
When first turned on; the console display should show
CODE.
3.4 Initializing Scoreboard
Enter the four digit code
(2310) shown in the lower center of the keyboard as in the
following example:
Push
F] 11 .

When the proper code has been entered, the console display will show 0000.
3.5 Team Scores
The Home and Guest Scores
can be changed in three different ways.
(A) To add
1 to the existing Ecore: Push m.
(B) To directly enter or correct a score: Push
followed by the desired number, then
ENTER
0
Example: Present Home Score is 15.
Change the score from 15 to 23.
Push: [El
v1
(E) To clear the score: Push
3.6 Game
Entry to the above function is made in the same manner as direct entry for Team
Scores.
4. MAINTENANCE AND TROUBLESHOOTING
4.1 Introduction
This section gives maintenanceand 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
A simple analog or digitalvoltmeter 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) Swreboard doesn't light and console doesn't work
(a) Check that the main power switch is turned on.
@) Replace any defective or blown fuses.
(c) Check the power connections and voltages at the scoreboard.
(d) Contact the Customer ServiceDepartment.
(B) Scoreboard digits don't light, but the console works
(a) With the main power switch "off'; remove the cover over the controller
assembly.
@) 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 ServiceDepartment.
(C) The scoreboard digits light but the console doesn't work
(a) Check for continuity between the scoreboard and the junction box.
@) 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 shield in the junction box, using a voltmeter set on the 12 VAC or higher
scale.
If the voltage is 0 VDC see the controller parts list for a transformer assembly.
If the voltage is less
than 8 VAC consult the controller wiring diagram for
instructionson 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 following voltages in the junction box, with respect
to the schield,
with a voltmeter set on the 3 VDC or higher:
Shield to
Red (Clock) = Approximately 1.0 VDC
Shield
to Black (Data) = Approximately 1.0 VDC
Shield to White (Sync) = Approximately .1 VDC
@) 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.
Q 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 "C" into
"D" and "D" into "C" locations.
@)
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.
@) 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.
