■Distinctive Ring Pattern Detection (DRPD) Feature

(See p. 21)

Some companies offer a distinctive ring pattern (DRP) service that allows you to assign two or more telephone numbers with distinctive ring patterns to a single telephone line. By subscribing to such a service, you can have both a fax number(s) and a telephone number(s) for your FAXPHONE using only one phone line.

When a call is made, the FAXPHONE checks the incoming ring pattern and knows if the call is from another fax unit or from a telephone.

Fax Only Mode __________________________________

The FAXPHONE is set up at the factory for both fax transmission and telephone calls. If you have a dedicated fax line, you need to set the FAXPHONE to Fax Only Mode.

■Setting Fax Only Mode

When you set the FAXPHONE to Fax Only Mode, the unit picks up every call and automatically treats it as a fax transmission.

The FAXPHONE cannot receive automatically if you are making copies, printing reports, or registering information. See p. 68.

■Receiving documents in Fax Only Mode

When the FAXPHONE is set to Fax Only Mode, it automatically receives documents whenever a call comes over the fax line.

1 Make sure the FAXPHONE is set to “Fax Only Mode” (see above).

The FAXPHONE assumes all incoming calls are from another fax machine sending a document. It receives the documents automatically.
