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 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 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.
