2.  Verify the symptoms by attempting to re-create the failure by running the 
diagnostic test or by repeating the same operation.
Note: To run the diagnostics, refer to “Running the Diagnostics”.
3.  Use the following table with the verified symptom to determine which page 
to go to. Search the symptoms column, and find the description that best 
matches your symptom; then go to the page shown in the “Go To” column.
