Final Setup Instructions
After correctly setting the necessary jumpers make sure to replace the clock cover before powering
up the clock. Read over Chapter 6 for a detailed understanding of the clock behavior during startup.
Configure clock operation through the utility software (the Utility), or through the front panel
keys. Chapter 7 discusses configuring the clock functions remotely using the Utility and Chapter 8
discusses configuring the clock using the front panel interface.
For additional technical detail concerning timing signals, please see Chapter 9.
