viiAbout this ManualThe ATLAS 550 system consists of the Base Unit, at least one network module, and one or more optionmodules. (Each network/option module includes its own user manual which contains specific infor-mation about installing, configuring, and testing the option module; insert the option module manualsinto this binder.) The ATLAS 550 User Manual provides the information you need to install, configure,test, and troubleshoot theATLAS 550 system; when applicable, this manual refers you to the individ-ual network/option module user manual. The arrangement of this user manual allows you to quicklyand easily find the information you need.
