Error Information 
 
The failure that might occur includes the temperature of the mainboard is too high, 
the fan stops rotating, etc. If failure occurs, users need to return the instruments 
back to our factory for repair. At most 16 error messages lately appeared can be 
viewed. The error information is stored in the volatile memory and will be cleared 
automatically after power-off. 
 
If there are error messages in the oscilloscope currently, an exclamation mark is 
displayed in the status bar at the lower-right corner of the screen; at this point, you 
can press Utility  System  ErrorInfo to view the error messages. If the 
oscilloscope works normally, ErrorInfo is grayed out and disabled.
