1.7.1 Explanation Of Light Patterns
The lights on your telephone alert you to different conditions by
turning on and off in a certain pattern. You will observe the following
light patterns on your speakerphone or monitor telephone:
Flashing. The light flashes on and off at equal times (about 1/2 second
on and 1/2 second off).
Winking. In contrast to flashing, the light goes off for a very short time
compared to the time it is on.
Fluttering. Afluttering light is about eight times faster than a flashing
light.
