This number of rings can be changed to a maximum of 4. See “Setting the number of rings to
answer in the TEL/FAX mode” on page 25.

Notes:
• The unit can distinguish between a voice and fax call by detecting the calling tone (CNG), sent by the
transmitting fax machines.
Some fax messages that are transmitted manually may not send with a calling tone. These calls must be
manually received after the unit rings and the call is answered.
• If you hear the facsimile unit ringing, you can pick up the handset on the facsimile unit or another
extension (if connected on the same line) to answer the call.
