171FaxNOTE: The Caller ID service varies with different carriers Contact your local telephone company to learn about theservice available in your areaExternal TAD (Telephone Answering Device)Related Models:Dell E515dn / Dell E515dwYou can connect an external Telephone Answering Device (TAD) to the same line as your machine. When the TADanswers a call, your machine will “listen” for the CNG (fax calling) tones sent by a sending fax machine. If it hearsthem it will take over the call and receive the fax. If it does not hear them, it will let your TAD take a voice messageand the display will show Telephone.The external TAD must answer within four rings (we recommend setting it to two rings). This is because yourmachine cannot hear the CNG tones until the external TAD has picked up the call. The sending machine will sendCNG tones for only eight to ten seconds longer. We do not recommend using the toll saver feature on your externalTAD if it needs more than four rings to activate it.Unless you are using Distinctive Ring, the TAD must be connected to the EXT. jack of the machine.• If you subscribe to your telephone company’s Distinctive Ring service:You may connect an external TAD to a separate wall jack only if you subscribe to your telephone company’sDistinctive Ring service, have registered the distinctive ring pattern on your machine, and use that number as afax number. The recommended setting is at least four rings on the external TAD when you have the telephonecompany’s Distinctive Ring service. You cannot use the Toll Saver setting.• If You Do Not Subscribe to the Distinctive Ring Service:You must plug your TAD into the EXT. jack of your machine. If your TAD is plugged into a wall jack, both yourmachine and the TAD will try to control the telephone line. (See the illustration.)
