aemmmmMm
Your machine has a special feature 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 36.
