Tip: Log data are confirmed online by establishing communications between the SX-2000SM and a
PC. For details, refer to the separate Setting Software Instructions, "Utility."
Confirm the cause of failure or abnormality on the log data (in this example, the log data that the
speaker terminal for the zone 2F is open state is listed), then fix the fault part.
