SERVICE REQUIRED TESTS
Each time the game returns to its Attract Mode the program checks the error log. If errors are found, the
Operator Alert Signal will appear at the lower left corner of the Attract screens if the computer verifies a
fault. The operator can inspect the game condition at a glance without entering the Menu System.
Once the red dot has appeared on screen, the operator must take action. Unlock and open the coin door.
Press and hold the TEST button to enter the Menu System. Test the controls, monitor, sound, disk drive,
etc. until the problem area can be determined. If the calibrate and repair routines do not resolve the
problem, refer to the Troubleshooting Chapter for assistance. Make repairs or adjustments as necessary.
When the cause has been corrected, the indicator automatically disappears from the screen.
SWITCHES AND JUMPERS
There are a number of hardware variables that can be changed to adapt the electronics to other uses.
Jumpers determine which circuit paths are active, and DIP Switches select instructions.
Switches
The CPU Board push button switch Sl is near the larger heatsink. This switch resets the processor. This
switch is used during service to restart the game without cycling the power off and on again.
There are two DIP Switch blocks (U13 and U17, near the center of the Sound I/O Board Assembly).'Each
consists of eight individual switches. These switches are factory set for normal game operation.
NOTE: A/I instruction variables for this game are software selectable from the menu system. Each
DIP Switch should be set to its OFF position (Factory default) for proper game operation.
Jumpers
Jumpers on the CPU Board match various system characteristics to optimize the memory circuits and
video signals. These jumpers may require adjustment to accommodate future upgrades or service.
N O T E : The circuit paths are optimized at the factory during the final board test procedure. Each
jumper should be left in its original position to avoid error messages or video sync problems.
ERRORS
The system detects errors at start up or during various diagnostic tests or operations and reports them on
the screen. Some errors, such as minor disk data faults, are automatically repaired by the system. Other
errors, such as player control calibration, are fixed by manually resetting the values in game memory. In
most cases, the game will continue to operate with reduced performance after discovering minor errors.
Always record error messages before attempting to correct any problem. The USER MESSAGES report
may store some additional temporary messages (refer to STATISTICS earlier in this section).
After recording the error messages, turn off the game's power, wait a few minutes, then turn the power
back on again. Pay attention to the start-up screens and note any error messages during the Power On
Tests. If possible, enter the SELF TEST MENU SYSTEM and run all of tests related to where the errors
occurred. Record any new error messages and compare them to those previously recorded to determine
whether the errors are random or continuous in nature.
N O T E : Do nor ignore error messages even when the game can be forced to start and operate.
Games with errors may generate reduced earnings due to poor performance.
