AUTO BURN-IN MODE.
The Auto Burn-in Mode permits the operator to check intermittent (or nonrecurring) problems
associated with most portions of the game's 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:
1.
While in the Game Adjustments, reach Ad 67 and change the Factory Setting of NO to YES, via
the Credit button. Set the AUTO·UP/MANUAL·DOWN switch to AUTO-UP.

SYSTEM-11 B MEMORY
CHIP
TEST.
A new feature is now included in the Memory Chip Test for System 11B. During power-up, the CPU
performs a self-testing routine. When all tests are satisfactory, the game proceeds to the
Att£a.Q.t
~.
allowing players to use the game. Whenever a portion 01 the lesting does not produce
satisfactory results, the game displays a message, before proceeding to the next portion of the
testing. ONLY after all tests are satisfactory does the game allow play to begin.
In addition to the displayed message, when any part of the self-test
routine fails, 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-test
routine by pressing the CPU Diagnostic Switch (SW 2) on the edge of the CPU Board.
