A point is sconed when tlre ball passes thnougl'l the opponentrs goal 6p63s, and
the scones ane momentanily Flashed on the scneen until the next serwe. Making :
a goal at the opponentrs side produces a higher sccre fon youn side.
The game is played in this Fashion until the tir:ie line completely disappeans.
MCDE #2: IFthe mode selecton switch is set tc; ncsition rr2", the machine will
be conditioned to "sc1id playens vs. checked i:iayenstt and the game sequence is
as Follows: Coin irrsention lights the credit lamp inciicating thene is game cnedit,
and the game commences when the stant switcr. cuttcn is pnessed.
The CRT configunation displayed Fon this rncce is a playtield in which thene ane
two types oF playens; solid men and checkec men. One playen ccntnols the solid
team and anothen cpenates the checked tearn. However, if desined, one on two
playens may openate each team so that thr^ee on toun playens may be accomo-
dated.
When the machine is conditioned to make *2, =e::i^' si.de has Five men: two for-
wands, two backs and one goalie. Each side nas ruro potentiometens (irpotstr):
orre pot contnols the icnvar^ds and the othen c:r:n:is the deFense men (the backs
and the goalie). Each side also has a goal ar'^=a =nd both goais ane cF equal

K. Tnoubleshooting
The tinst step in any trrcubleshooting pnocedurle is to obserwe the chanactenistics
oF the malfunction. With these clues in mind, examine the aneas of the machine
o & M - 13

which might cause tlrese symptoms. Fon example, if thene is no powen, check
the hanness, not the PCB, Likewise, iF part oF the playField display is missing,
check the PCBrnot the hanness on T.V.
Thnee majon aneas oF the machine can be isolated Fon tncubleshooting punposes:
the T.V., the PCB and the hanness. The hanness inciudes the fuses, the tnans-
Fonmen, the intenlock switches, the A.C. iir"e iilten, the stant and ccin switches,
the antenna wine, the potentiometens and kick swi.tches, ai1 plug-in type connec-
tons, the PCB edge connecton art aii ihe inten::nnecting wines.
