Using manual dial
Normally, the product dials after you press fax/send. At times, however,
you might want the product to dial each number as you press it. For
example, if you are charging your fax call to a calling card, you may need
to dial the fax number, wait for the acceptance tone of your telephone
company, and then dial the calling card number. When dialing
internationally, you might need to dial part of the number and then listen
for dial tones before continuing to dial.
