circuitry. Repeatedly cycling through a group of tests can sometimes bring
a problem. which occurs only randomly or occasionally. to exhibit itself
more frequently. thereby aiding in the isolation of the problem. To activate
the Auto Burn-in Mode:

DOWN switch to AlITa-UP.

nature of the problem; then. perform necessary repairs.)
System-llB Memory Chip Test
A new feature is now included in the Memory Chip Test for System IlB.
Durtng power-up. the CPU performs a self-testing routine. When all tests
are satisfactory, the game proceeds to the Attract Mode. allowing players to
use the game. Whenever a portion of the testing does not produce
satisfactory results. the game displays a message. before proceeding to the
next portion of the testing. ONLYafter all tests are satisfactory does the
game allow play to begin.
In addition to the displayed message. when a test falls. LED2
('DIAGNOSTIC')mounted on the CPU Board can be observed to determine
the probable cause of the problem. This LED blinks. or flashes. a certain
number of times to identify the probable cause, as described in the CPU
LED Indicator Codes Table. The operator can also start the self-testing
routine by pressing the CPU Diagnostic Switch (SW2) on the edge of the
CPU Board.
