number with decimal point which is displayed just after the LED's flash in the power up
sequence.

during power up. Additional checks are made when data is received in the form of MIDI
System Exclusive messages. When an error is detected during power up, one or more error
messages will be displayed. The following chart shows the error code that will be displayed
in the event of a problem, the cause of the problem, and the appropriate action for you to
take. Diagnostic status is also available via MIDI System Exclusive messages. For
