this arrangement, only while
both
access doors arc closed is
the AC power allowed to reach the game's power supply,
meaning that the game can operate.
After application of AC power per paragraph 4.2.1
above, correct operation of the interlock switches can be
checked in two steps, as follows:
Step 1) Unlock and open the upper rear panel access
door. The correct response is that by the time
the edge of the door has moved about 2 to 3
inches away from the cabinet, the TV screen
should go dark, verifying that the interlock
switch has automatically transferred to "off."
While opening the access door, do not insert
fingers inside the cabinet, and do not allow
foreign objects to fall inside. If images are
still present on the TV screen even after the
door has been opened, immediately close and
lock the door, and unplug the power cord
from the wall outlet. Then refer to Section VI
of this manual to replace and/or adjust the
interlock switch. If the correct response was
obtained, then close and lock the access door.
Step 2) Unlock and open the lower rear panel access
door. The correct response is the same as
described in Step 1 above. If the correct
response is obtained, then close and lock this
access door also.
Do not go on to the remaining paragraphs in this section
until the operation of both interlock switches has been
checked and found to be correct.
4.3 GAME STRUCTURING
Before putting the game into operation at the game site,
the game structuring should be defined by the owner/oper­
ator. The term
game structuring
refers to the game rules and
the maximum length of the overall elapsed game time per
play. Para. 3.4.7 ofSection Ill in this manual covers the
owner/operator options provided in this game and describes
their effect on game structuring.
Adjustment of the 6-players-per-coin/2-players-per-coin
option consists of manually changing the position of a two­
position switch mounted on the printed circuit board inside
the cabinet. Adjustment of the 2-minute/90-second game
time option consists of soldering or unsoldering two adja­
cent points on the surface of the printed circuit board.
Before performing either adjustment, the game should
be de-energized or not operating_ Further, it is also recom­
mended that the power cord be unplugged beforehand.
Unlock and open the lower rear panel access door;
doing this should cause the interlock switch to de-energize
the game, as described in para. 4.2.2. If the interlock switch
fails to de-energize the game, then immediately close and
lock tile doOI, unplug 1hr power cord, and refer to Section
VI of this manual to adjust and/or replace the switch.
While being careful to avoid touching any parts of your
body against the TV chassis components or other wiring
connections inside the cabinet, find the printed circuit
board.
4.3.1 ADJUSTMENT OF 6-PLA YERS-PER-COIN/
2-PLAYERS-PER-COIN OPTION: On the PCB find the
switch mounted near the board's lower edge, approxi­
mately halfway from each end of the board. The location
of this switch is shown on drawing number A003750.
Note the letters "AP"* and "A" engraved on the board's
surface, alongside the switch.
To structure the game for 6 players/coin, manually
slide the switch stud toward the letter "A" as far as it will
go. To structure the game for 2 players/coin, manually
slide the switch stud toward the letters "AP"* as far as
it will go.
After doing this, make sure that no foreign objects have
been dropped inside the cabinet, and then close and lock
the access door.
4.3.2 ADJUSTMENT OF 2-MINUTE/90-SECOND
GAME TIME OPTION: Remove the PCB from inside the
cabinet by unplugging its edge connector and sliding the
board all the way out of its guides. Then find the two PC
traces which comprise the jumpering point located between
the IC devices in board positions H3 and J 3 (see Figure 4-1).
If these two stripes are left
not
connected, the maximum
elapsed game time per play will be 90 seconds; if they
are
connected by soldering, the maximum elapsed game time
per play will be 2 minutes.
CAUTION: He careful not to apply excessive
heat when touching a soldering iron to the
traces. Excessive heat can damage the traces,
causing them lo peel up from the surface of the
board. A 40-watt iron with a small tip designed
for IC work is recommended for this task.
After the adjustment has been made, by either soldering
or unsoldering the jumpering poirH, replace the PCB inside
the cabinet. Make sure that the PCB edge connector is plugged
in securely and in the correct orientation. Also make sure
that no foreign objects have been dropped inside the cabinet.
Then close and lock the access door.
*Note: in future production runs, this "AP" position
instead will be labeled "2/4/6" on the board.
