Special Dialing Requirements
I need an “outside line.”
You may need to type a “9” or other number to reach an outside line if you are calling
from an office building (see “Dialing Prefix” on page 53). The exact method of dialing
will depend on the telephone system, but will be the same as any other telephone used
on that system.
I need to “pause” while dialing.
Type a comma ( , ) to pause for two seconds while dialing. For example (9, 222 5555).
This might be used when dialing an outside line with some office telephone systems.
I need to call long distance.
When dialing, type a “1,” the area code and the number before pressing .
Enter

How can I tell what is happening with the call?

The Superprint Pro80 LVD shows you the “call progress” using a
combination of the Display and the Signal light.
Most calls require two rings before the Superprint Pro80 LVD displays call
