Connecting an external telephone answering device (TAD) Sequence You may choose to connect an additional answering device. However, when you have an external TAD on the same telephone line as the MFC, the TAD answers all calls and the MFC "listens" for fax calling (CNG) tones. If it hears them, the MFC takes over the call and receives the fax. If it does not hear CNG tones, the MFC lets the TAD continue playing your outgoing message so your caller can leave you a voice message. The TAD must answer within four rings (the recommended setting is two rings). The MFC cannot hear CNG tones until the TAD has answered the call, and with four rings there are only 8 to 10 seconds of CNG tones left for the fax "handshake". Make sure you carefully follow the instructions in this guide for recording your outgoing message. We do not recommend using the toll saver feature on your external answering machine if it exceeds five rings. If you do not receive all your faxes, reduce the Ring Delay setting on your external TAD. 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's Distinctive Ring service, have registered the distinctive ring pattern on your MFC, and use that number as a fax number. The recommended setting is at least four rings on the external TAD when you have the telephone company's Distinctive Ring Service. You cannot use the Toll Saver setting. APPENDIX A A - 10
