To insert a pause or wait
You can insert pauses into a fax number you are dialing or programming
to a one-touch key, speed-dial code, or group-dial code. Pauses are
often needed when dialing internationally or connecting to an outside
line.
Press pause/redial to enter a three-second pause in your dialing
sequence. A comma appears on the control panel display, indicating the
pause will occur at that point in the dialing sequence.
