Connecting an external or
extension telephone 7
You can connect a separate telephone as
shown in the diagram below.
1 Extension telephone
2 External telephone
When you are using an external telephone,
the LCD shows Telephone.
Operation from extension
telephones 7
If you answer a fax call on an extension or an
external telephone plugged into the correct
socket on the machine, you can make your
machine take the call by using the Remote
Activation Code. When you press the Remote
Activation Code l 51, the machine starts to
receive the fax.
If the machine answers a voice call and
pseudo/double-rings for you to take over, use
the Remote Deactivation Code #51 to take
the call at an extension telephone. (See F/T
Ring Time (Fax/Tel mode only) on page 34.)
If you answer a call and no one is on
the line:
7
You should assume that you're receiving a
manual fax.
Press l 51 and wait for the chirp or until the
LCD shows Receiving, and then hang up.
Note
You can also use the Fax Detect feature to
make your machine automatically take the
call. (See Fax Detect on page 35.)
Using extension telephones
(For U.K. only) 7
Your premises may already be wired with
parallel extension telephones, or you may
plan to add extension telephones to your line,
as well as your machine. While the simplest
arrangement is a straightforward parallel
connection, there are some problems with
this arrangement, the most obvious of which
is inadvertent interruption of a facsimile
transmission caused by someone picking up
an extension telephone to make an outgoing
call. Also, Remote Activation Code may not
operate reliably in such a simple
configuration.
This machine may also be set to make a
delayed transmission (i.e. a transmission at a
pre-set time). This pre-set job may coincide
with someone picking up an extension
handset.
These problems can easily be eliminated, if
you arrange modification of your extension
wiring circuit, such that extension devices are
connected ‘downstream’ of your machine in a
master/slave configuration (see fig. 2). In this
configuration the machine can always detect
whether a telephone is in use. Thus it will not
attempt to seize the line during that time. This
is known as ‘telephone off-hook detection.’
The inadvisable configuration is shown in
figure 1, and the recommended master/slave
configuration is shown in figure 2.
