Notes
•
The audio buzzer that generates 1 kHz beeps is in the computer, inside the VGM (video game machine). If
you have difficulty hearing beep codes, remove the rear cabinet door and computer cover.
•
Arcade Computer circuit boards resemble those in personal computers. Yet Midway engineers
reprogrammed the boards for application in this VGM. Power-On Self-Test codes are unique to the Arcade
Computer in this VGM.
•
Wiring or peripheral circuit problems may not trigger on-screen error messages. You may discover difficulties
during Menu System diagnostic or calibration procedures.
•
For help with unresolved error messages, call your authorized distributor.
NOTICE:
Don’t attempt to move computer circuit boards into alternate slots. Midway
assigned boards to specific slots. The custom operating system won’t recognize
improperly placed boards, even though they function normally.
