5.1  Overview 
Introduction 
This section gives you all the information necessary to monitor and operate your recorder and for 
performing routine maintenance tasks. In this section assume that the recorder has been properly installed 
and configured, and that the inputs are properly calibrated. 
Some of the procedures in this section are required only initially, and some are required only randomly, as 
conditions dictate. Once the recorder is up and running, required operation actions are infrequent and 
straightforward. 
Review the Operator Interface, Display and Keypad descriptions shown in Section 1 Overview.
