TROUBLESHOOTING GUIDE
To use this guide, you need only to recognize the symptoms and follow the troubleshooting procedure until the problem Is
discovered. The method of troubleshooting requires the replacement of modules within the system. The first step Is to
determine which symptom listed best describes the problems encountered. Next, follow the troubleshooting procedure
until an error Is found. After each error Is corrected, assume a working system, return to the beginning and continue until
all errors are corrected and the system Is operational (no symptoms apply).
