TEST/DIAGNOSTIC
PROCEDURES
WILLIAMS ELECTRONICS GAMES 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 com-
prising 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 Auto
Burn-in Mode is available. Activating this
mode enables the operator to
observe the game while all of
the diagnostic
tests,
except the
switch
test, 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.
CAUTION
PIN‘BOT's System 1
1
game program has a
new
capability
to aid the
operator and service
personnel:
When the operator is beginning the
Test/Diagnostic Procedures (and also at
game Turn-On), a
dis-
play now signals when a
switch has NOT been actuated during
ball play for a lengthy
period of time
(60
balls, or
20
games).
However, for the Switch
Problem Reporting activity at the
beginning of the
Test/Diagnostic Procedures, the display of
problem switches is not limited to just three
switches; it
now
includes
ALL
switches exhibiting problems. Refer to
the text on Switch Tests
for additional
information. To proceed with the Test/Diagnostic Procedures,
use AUTO-UP, and
press ADVANCE.
