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 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 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.
3

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 Timer Display
1 ea Control Console (with 25' cable)
1 ea Service Manual
1 ea Press Box Junction Box
? ft MP-40 Control Cable (if ordered)
IMPORTANT!
The MP-40 cable supplied by ALL AMERICAN SCOREBOARDS for use on the
Microprocessor based timers is specifically designed for this system. Use of
a substitute cable may void the warranty on the scoreboard!
2.2 Mounting
For permanent mounting to wall, see the enclosed installation drawing in Section 6.
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.
4

2.4 Electrical connections
The MP-3913 timer requires a 120 VAC, 20 AMP circuit.
IMPORTANT !!!
To protect the MP-2002 control from damage, it is advisable to 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.

Turn on the power to the display. The display will show "0:00" .
3.2 Console Power
Push
ON/OFF once to turn the console on.
Push
ON/OFF a second time to shut the console off.
When first turned on; the console display should show CODE .
Enter the two digit code (94) shown in the lower center window of the keyboard as in the
following example:
Push CODE 9 4 ENTER .
When the proper code has been entered, the console display will show ON .
3.3 Console Display
The 4 digit Liquid Crystal Display (LCD) shows the information entered from the keyboard.
3.4 Display Setting and Control
To set 152, Push: SET 1 5 2 ENTER .
5

Any number up to 999 may be preset in a similar manner.
3.5 Dimmer
Push
DIM to alternately dim and brighten the lamps in the display.
WARNING
120 VAC wires are exposed whenever the cover over the controller assembly is
removed from the scoreboard. Use extreme caution during troubleshooting or repair.
To avoid possible damage to equipment or personal injury, always turn off the main
power before removing the cover or replacing assemblies, or replacing lamps.
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
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) Timers don'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 timers.
(d) If the timer still doesn't light, check the transformer voltage going to pins 5 & 6 of the data
input connector 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, check the voltage again at the control console end of
the cable.
6

If the voltage is less than 8 VAC, check the cables and connectors.
If the voltage is between 8-12 VAC, see the replacement parts list for a control or transmitter
PCB assembly, and contact the Customer Service Department.
(B) Timer 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 timer digits light but the console doesn't work
(a) Check for continuity between the timer 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 consult the parts list for a control console
and contact the Customer Service Department.
(D) The timer digits light, the console works, but there is no control of the timer.
(a) Check the voltage between the black and green 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 timer.
(d) If the correct voltage also appears at the timer, see the replacement parts list for a receiver
PCB assembly.
(E) The timer 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 "B" and "B" into "C" locations.
7

(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 timer works, but some lights do not come on.
(a) Check for burned out lamps.
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.
(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.
