Fatal Errors
AN-X2 monitors its operation for “impossible” conditions and generates a fatal error if it
detects one. It generates a fatal error code on the SYS (or MS) LED by flashing 8 bits
followed by a pause. The least significant bit is first, with green for 1 and red for 0.
If a fatal error occurs, record the SYS or MS LED sequence and contact technical
support.
