Test/Diagnostic Procedures
DR.
DUDE
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 s1mplyverify that all devices are working properly.
In order, these tests deal with the music, the displays. the lamps. the solenoids.
and the switches.
In addition to the diagnostic testing. a feature called the Auto Bum-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 AlITO-UP/MANUAL-DOWNswitch to MANUAL-DOWN.and press
the ADVANCEbutton.

during ball play for a lengthy period of time (~Oballs. or

Diagnostic Procedures, the display of problem switches now includes ALL
