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:
Flashing. The light flashes on an off at equal times (about 1/2 second
on and 1/2 second off).
Winking. In contrast to flashing, the light flashes off for a very short
time compared to the time it is on.
Fluttering. A fluttering light is about eight times faster than a flashing
light.
