GMC Board Alarm Codes
There is an LED on the GMC board that displays any board errors.
The error code can be identified from the flashing LED using the
following table. In the case of more than one error, the error with
the highest priority will be displayed until it is resolved.
In the case of normal operation, the LED flashes at a frequency of ½
Hz. In the case of an error, the LED remains off for 4 seconds, then at
a frequency of 1Hz, it flashes a number of times equal to the error
