Connecting an External Telephone Answering Device 
(TAD)

Sequence

You might choose to connect an additional answering system.  When you have an 
external TAD on the same telephone line as the fax machine, the TAD answers all 
calls. The fax machine “listens” for fax calling (CNG) tones. If it hears them, the fax 
machine takes over the call and receives the fax. If it doesn’t hear CNG tones, the fax 
machine 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 
fax machine cannot hear CNG tones until the TAD has answered the call, and with 
four rings there are only 8–10 seconds of CNG tones left for the fax “handshake.”  
Make sure you carefully follow instructions in this manual for recording your 
outgoing message. We do not recommend using the toll saver feature on your external 
answering machine if it exceeds 4 rings.

Do not connect a TAD elsewhere on the same phone line—your fax machine and 
TAD will both try to control the line.
