Notes
1.
The audio buzzer that generates 1 kHz beeps is on the computer, inside the VGM (video game
machine). If hearing beep codes is difficult, remove the cabinet doors and computer cover.
2. Arcade Computer circuit boards resemble those in personal computers. Yet Midway engineers
reprogrammed the boards for application to this VGM. Power-On Self-Test codes are unique to
the Arcade Computer in this VGM.
3. Wiring or peripheral circuit problems may not trigger on-screen error messages. You may
discover difficulties during Menu System diagnostic or calibration procedures.
4.
Call your authorized distributor for help with unresolved error messages.
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.
