If you have pulse dialling service, but need to send tone signals (for telephone banking, for example), 
follow the directions below. If you have touch tone service, you do not need this feature to send tone 
signals.

Lift the external telephone’s handset and dial the number.

When you are asked to enter any number, press # on the control panel of the machine. Any digits 
dialled after this sends tone signals.

When you hang up, the machine returns to pulse dialling service.

When you share one line for your telephone and fax machine, in the Fax/Tel (F/T) Mode, the 
machine can determine whether an incoming call is a fax or a telephone call. (See Select Receive 
Mode, page 25.)

This key is used to enter into a telephone conversation having picked up the handset of an external 
telephone in F/T pseudo-ringing.

Also, if you press Tel when you are talking lifting the external telephone’s handset with the other 
end, you can hear the other end from machine’s monitor speaker, but the other end cannot hear you.
