If you answer a fax call on an extension or an
external telephone, you can make your
machine take the call by using the Remote
Activation Code. When you press the Remote
Activation Code

, 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
# 5 1
to take
the call at an extension telephone. (See
If you answer a call and no one is on

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 on next
page). 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.’
