Three light indicators (LEDs) form the user interface of the Nokia 30. The LED user interface
is shown in Figure 2. 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 in Table 1, Table 2, and Table 3, respectively. All three
LEDs can also be configured so that they will not show any status and will stay off during any
operation.
