TEST/DIAGNOSTIC
PROCEDURES
WILLIAMS
ELECTRONICS
GAMES also
provides a
series of
diagnostic tests to aid
the operator
in
determining game
condition
(that
is,
whether the game's features
and highlights
are
operating
satisfactorily).
These
tests activate
virtually
all
the electronic
and
electromechanical
devices
comprising the game, so that the
operator
can
readily
locate
a
malfunctioning
device or
simply
verify
that all
devices
are
working properly. In
order,
these
tests deal
with
the
music, the displays,
the
game
sounds, the
lamps,
the solenoids, and the switches.
In
addition
to the diagnostic testing,
a feature
called
the is
available.
Activating
this
mode
enables
the
operator
to
observe the
game
while
all
of the diagnostic tests,
except
the
switch
tests, occur.
This
can
be
very
helpful
in
locating
‘intermittent’
problems.
Activating
either
the
entire test series or one
of the individual tests
requires use of
the Game
Adjustment/
Diagnostic
switches.
Open the
coin
door for access to these
switches. To
proceed
to
the
Diagnostic
Tests,
the operator
must
simply
switch
the game On,
set the
AUTO-UP/MANUAL-
DOWN
switch
to
MANUAL-DOWN,
and
press
the
ADVANCE button.
