User Interface Features
Three light indicators (LEDs) form the user interface of the TME-3.
LED 1 shows the terminal status, while the other two are reserved for the application
module following start-up.
During start-up and special operations, all three light indicators are in terminal use. The
functionality of the light indicators in start-up, normal, and special situations is
described below.
All three LEDs can also be configured so that they will not show any status and will
remain off during any operation.
