GENERAL INFORMATION
Lights
Indicator lights provide silent visual reminders to the voice terminal user regarding lines, features,
and messages taken at other locations. The lights on DEFINITY G1, G2, G3, and System 75 and
85 voice terminals are light-emitting diodes (LEDs) or neon lights.
On all multi-appearance voice terminals, each call appearance/feature button has two indicator
lights: a red light and a green status light. When a call appearance/feature button is used for a
feature, only the status light is operational; the red light remains off at all times. Feature-only but-
tons have either a single green status light or no light at all. The various arrangements of red and
green lights are shown in Figure 2.
