Troubleshooting 
The troubleshooting procedures are divided into two parts: 
  Self Diagnostics - Error Message Prompts, and 
  Visual Failure Symptoms. 
If a “Failed” indication is given for one of the power-up tests and/or an error message prompt blinks in the 
lower display, refer to the Self Diagnostic error message prompts. 
If erratic operation is observed, refer to the Visual Failure symptoms. 
In either case, run the status tests to verify the status of the recorder’s basic self-diagnostic tests.
