Troubleshooting                                                         General/ - 1


                  General
                  The Symptom Charts included in this chapter will help you
                  diagnose specific symptoms related to your product. Because cures
                  are listed on the charts in the order of most likely solution, try
                  the first cure first. Verify whether or not the product continues to
                  exhibit the symptom. If the symptom persists, try the next cure.
                  (Note: If you have replaced a module, reinstall the original module
                  before you proceed to the next cure.)

                  If you are not sure what the problem is, or if the Symptom Charts
                  do not resolve the problem, refer to the Flowchart for the product
                  family.
