Solo Lite US Distinctive Ring "Distinctive ring" is a service provided by a telephone company. You need to check with your telephone company to see if it is offered in your area. If it is offered, it allows you to have two or three phone numbers on the same phone line and is cheaper than having separate lines. It is easy to tell the phone numbers apart because each one has a distinctive ring: the first phone number has a single ring, the second has a double ring, and the third has a triple ring. The Distinctive Ring feature allows the HP OfficeJet to distinguish between voice and fax calls when both are received on the same phone line, but it only works with your telephone company's distinctive ring service. The factory setting is Distinctive Ring=Off; the HP OfficeJet automatically (Receive mode is set to Auto) answers all calls. If you have subscribed to your telephone company's distinctive ring service, ask your telephone company to assign the single ring to phone numbers that receive voice calls and multiple rings to phone number(s) that receive fax calls. Then Check the Distinctive Ring checkbox to allow the HP OfficeJet to answer the phone and receive faxes only when it detects a multiple ring. (At the time of publication, distinctive ring services`also known by other namesw` ere available only in certain parts of the U.S. and some Asian countries.) Silent Detect To receive faxes from older-model fax machines that don't emit a fax signal, click the Silent Detect checkbox.
