How to Use the Symptom Charts
 
The Symptom Charts included in this chapter will help you 
diagnose specific symptoms related to the product. 
The steps to solve a symptom are listed sequentially. You might not 
need to perform every step before the symptom is solved. Start 
with the first step, and then test for the symptom. If the symptom 
persists, replace any modules you removed, go to the next step, 
and test again. Continue down the list until the symptom is solved.
