INTRODUCTION
CONGRATULATIONS! on purchasing our Overhead Bonus Jackpot Display. This
display is used in combination with 2 – 8 linked “Slam ‘n’ Jam” Basket Ball games. It
has a ‘HIGH SCORE’ feature, which means when a player matches, or beats that score,
they win the displayed bonus tickets in addition to their game tickets.
The display is fully adjustable with operator adjustable winning score that can
automatically decrement if programmed. The bonus ticket amount is also
programmable, and can increment automatically if required. For more information,
refer to the Programmable Adjustment section of this manual.

CAUTION
DO NOT
Attempt to test the logic boards (PCBs) with ordinary test equipment as this may result
in damage to digital components.
DO NOT
Connect or disconnect any of the logic boards’ integrated circuit modules (ICs) while
the power is ON.
!"
Mains AC power should always be turned OFF and the game
unplugged, before replacing any parts.
!"
When unplugging the game from an electrical outlet, always
grasp the plug, not the line cord.
!"
The Overhead Display should be grounded with a securely
connected ground line.
DO NOT
Subject the “Overhead Bonus Jackpot Display” to extreme temperature variations.
Reliability of electrical components deteriorates rapidly over 60oC.
DO NOT
Expose the game logic boards to U.V. radiation (eg. direct sunlight) as this could
eventually corrupt the program.
DO NOT
Install the Overhead Bonus Jackpot Display outdoors or in areas of high humidity,
direct water contact, dust, high heat or extreme cold or in areas that would present an
obstacle in case of an emergency, ie. near fire equipment or emergency exits, or an
unstable surface or surface subject to floor or other vibration.
IF A PC BOARD SHOULD NEED SERVICING, CONTACT YOUR NEAREST

HANDLING PRECAUTIONS
When installing or inspecting the Overhead Bonus Jackpot Display, be very careful of
the following points and pay attention to ensure that the player can enjoy the game
safely.
!" Be sure to turn the power OFF before working on the Display or machine.
!" Make sure the power cord or the grounding wire is not exposed on the surface
(floor, ground, etc.). Make sure that grounding connections are made safe.
!" Do not use any fuse that does not meet specified rating.
!" Make complete connections for the IC Board and other connectors. Insufficient
insertion is very dangerous.
!" The operating (ambient) temperature range is from 5oC to 40oC.
!" Only qualified personnel to inspect or test the IC boards.
!" Only use a logic tester for testing IC boards. The use of a continuity tester is not
permitted. After confirming that there are no irregularities, turn the power ON.

FITTING THE OVERHEAD DISPLAY
!" The Overhead Display can be fitted in two positions, depending if it is fitted
above an “even” number of machines, or an odd number of machines. The
mounting brackets and the fitting of the brackets are the same for both an odd
and even bank of machines. The difference is in the position where they are
bolted onto the back of the display is different. Refer to diagrams below:

LINKING THE OVERHEAD DISPLAY continued
After cabling the machines as per diagrams, set all basketball game machines to
“Slave” (Program Adjustment P 01 set to 2). For more information on linking refer to
the “Slam ‘n’ Jam” Game Manual.
When an overhead display is fitted, it is automatically the “Master” and can not be
changed, so therefore, all other machines must be slaves. After these settings are
done, the machines should link when powered up. If you have any problems with
linking, refer to “Troubleshooting the Link System” Page13 of this manual.

TROUBLESHOOTING THE LINK SYSTEM
COMMON PROBLEMS:
WHEN GAMES WON’T LINK (ERROR Er4 is displayed on the
overhead display)
!"
Check that all link cables are tightly connected and go correctly from IN of one
machine to OUT of the next machine in a continuous loop. Refer to diagrams,
Page 6 to 9.
!"
Check that there is only one ‘MASTER MACHINE’ (This is ALWAYS the
Overhead Jackpot Display), and ALL the game machines are ‘SLAVE
MACHINES’. (Program adjustment P01).
!"
By checking what the displays show on ‘POWER UP’; can help diagnose where
a break or bad connection in the link could be. Refer to diagram below:
* NOTE: If, is displayed on more than one machine it means that
there is more than ONE ‘MASTER’. error is only displayed on a master
machine that is automatically the Overhead Jackpot display. Change any other
games displaying Er4 to ‘SLAVE”.

!"
Check the link cables for continuity with a multi-meter if a cable problem is
diagnosed.
!"
If there are still problems linking a large bank of machines, try linking the
‘OVEHEAD JACKPOT DISPLAY’ machine with just one machine at a time to
check there is not an internal problem with any one machine. After linking two
machines successfully, try introducing other machines one at a time.
!"
A single machines internal linking hardware and cables can be checked by setting
the single machine to ‘MASTER’ and looping the cable from OUT to IN as per
the diagram below:
!"
Turn the single machine off and on and the 3 digit display should show the
following sequence:
!"
If an error occurs, this would mean that the single link cable is faulty, or
the internal machine hardware is faulty. (If the machine hardware is faulty, contact
your nearest LAI Games Distributor).
* NOTE: If games will not link, the ‘OVERHEAD JACKPOT
DISPLAY’ will try for approximately 60 seconds, and if unsuccessful, the
games will power up as solo machines and the overhead jackpot display will no
t
be active and continue to display Er4.

* REMEMBER *
After performing this test, don’t
forget to set the machine back to
its correct P01 setting.
