g GUI display
g LED display
Startup errors are displayed in two patterns.
· MAIN CPU/DSP detects the errors and display it in the form of "Error E-XXXX" on GUI.
· Each CPU detects the errors and display it with the lighting pattern of the debug LED for each CPU or LED on Unit.
+ It is specifications,
the debug LED all turning off for 1 minute.
Refer to "5.3 TROUBLESHOOTING" for the equivalence method to each error.
