Lights
Each line button, each calling feature button, and some Auto Dial buttons have a
green light and a red light. The meaning of these lights varies, depending on
whether a button is used to access an outside line, a calling feature, or an
intercom Auto Dial number.
Table 3-1 shows the meanings of the various light patterns for each possible
button assignment.
