If necessary, you can use the following settings to improve the response of the
answering machine connection to incoming calls,
This function causes the fax machine to take over the line and begin reception if a
certain duration of silence is detected after the answering machine answers,
Time selections for the period of silence are 1 to 10 seconds. Quiet Detect Time has
been set to 4 seconds at the facto~. This gives the best performance with most
answering machines; however, you may need to adjust this setting depending on
the disconnect time of your answering machine.

Some answering machines may have unusually fast disconnect times (equal to
or very slightly less than 4 seconds), which means that the answering machine
may disconnect the line before fax reception can begin. In this case, try a Quiet
Detect Time setting of about 3 seconds.

function called "Quiet Detect Time" to detect the transmission. This function causes
your fax to disconnect the answering machine and begin reception if it detects a
certain duration of silence.
Your fax is set to automatically begin fax reception if it detects a duration of silence
of 4 seconds. When the person faxing presses their Start key, the line will go quiet,
and the transmitting fax machine will wait for a reception tone from your fax. Your
fax will therefore disconnect the answering machine 4 seconds after the key is
pressed, and send a reception tone to tell the other fax machine to begin
transmission.
If your answering machine has a fast disconnect time and disconnects the line
before 4 seconds elapses, fax reception will not be possible. In this case, you must
shorten the Quiet Detect Time setting as described on the following page. On the
other hand, if the Quiet Detect Time setting is too short, your fax may interrupt voice
callers if they pause during their message or if there is a period of silence in your
outgoing message.
