O ENABLE DISABLE RECOGNITION OF THE RING
FREQUENCY
In some countries, local telephone companies offer the pos-
sibility of assigning the same telephone line two or
more numbers , corresponding to different users. When
an incoming call is received, a different ring frequency
will indicate which user is to answer the call.
This function is extremely useful in the home or small offices,
where the same telephone line is shared by more than one
person.
Your fax machine is capable of "learning" one of
these frequencies (see the procedure that follows). In
this way, when a call with the specific ring frequency is
received, the fax machine (in " PHONE/FAX " and " TAD/
FAX " reception modes) prepares exclusively to receive a
document.
This function is particularly useful when associated
with silent reception in that the fax machine will only ring
if the call is coming from a telephone.
We recommend you disconnect the TAD before carrying
out the recognition procedure.

O CHANGE THE LENGTH OF THE ACOUSTIC SIGNAL
This function is only enabled in some countries.
When the fax machine is set up for automatic reception
with recognition of the type of call , it behaves as
follows:
• if it is being called by a fax machine , it will automatically
prepare to receive a document after the preset number of
rings
• if it is being called by a telephone , it will emit an acoustic
signal for a time of 20 seconds, after which, if you still have
not lifted the handset, it will automatically prepare to re-
ceive a document.
If you want, you can change the length of the acoustic signal
as follows:

O CHANGE THE SILENCE LAPSE
This function is only enabled in some countries.
Remember that if the silence lapse set on the external
answering machine is shorter than the one set on the
fax machine, the latter will never be able to automatically
prepare to receive a document in that the answering ma-
chine is activated first and, if no answering message is
heard within the preset number of seconds, it closes the
connection.
At this point, you must reduce the silence lapse set on
your fax machine so that it connects to the line first.
To change the silence lapse set on your fax machine, pro-
ceed as follows:
