Your machine has a special feature used in conjunction with an optional service provided by many local telephone
companies. It can distinguish up to 4 telephone numbers with a corresponding ring pattern identifying each
number. ”DRD” lets you provide multiple phone numbers, one for your fax, business or personal use with only
one single phone line.
Please check with your local telephone company on the availability of this service in your area.
Your machine can be programmed to respond to only 1 of the 4 distinctive ring patterns. To select the
corresponding ring pattern for your fax number, refer to the Fax Parameter Table on page 40.
