Notes on LED Indicator Status
1. LED 1 monitors CPU power (+3.3V). If this LED is off or blinking, investigate processor circuits. If other
LED’s are off or blinking at the same time, check +5V circuits or the game power supply.
2. LED 2 flashes when the hard disk is operating during game play. LED 2 may light continuously during
start-up. If this LED remains lighted, the hard drive may be locked-up or faulty.
3. Software controls RP63. In this game, RP63 initially indicates program start-up stages. This LED is a
seven-segment, alphanumeric display device. Normally, RP63 will display a lowercase “b” or “o” pat-
tern with sequentially blinking segments. During Self-Test screens, RP63 displays a “bouncing bar”
that resembles a hypen (“-”).
