6. LED of PC4000E

6.1 LED Indication at Emulator Startup

The emulator checks the PC4400 system immediately after startup. During system check the
PC4000E's SAFE LED flashes and the ERROR LED stays on steady. If the SAFE LED does not flash,
it means that the system check program is not operating. In such a case, check whether the PC4000E,
PC4400 card cage and each circuit board are fitted correctly. When the system check is completed,
the emulator status is indicated by the LEDs on the PC4000E.
Table 6.1 shows the LED indications at startup of PC4400.
