The LCD displays status messages as requested via the Device Health and Status branch of the front panel menu (see the Device Health and Status section in Chapter 4, Maintenance). In addition, the highest level status message appears on the front panel automatically if no front panel action has occurred at the E1 NTU for the past five minutes.

The LCD also lists commands, configuration options, and test results. In most cases, the top line shows the command or option name and default value, while the second line displays options and responses. When a response is required, select from the options displayed directly above the Function keys (F1, F2, F3); make your choice by pressing the corresponding Function key.
