Connections
The external TAD must be connected as
shown in the previous illustration.
1Set your external TAD to one or two
rings. (The machine’s Ring Delay
setting does not apply.)
2Record the outgoing message on your
external TAD.
3Set the TAD to answer calls.
4Set the Receive Mode to
External TAD. (See Choosing the
Receive Mode on page 4-1.)
Recording outgoing message (OGM)
on an external TAD
Timing is important in recording this
message.
1Record 5 seconds of silence at the
beginning of your message. (This allows
your machine time to listen for the fax
CNG tones of automatic transmissions
before they stop.)
2Limit your speaking to 20 seconds.
Note
We recommend beginning your OGM with an
initial 5-second silence because the machine
cannot hear fax tones over a resonant or loud
voice. You may try omitting this pause, but if
your machine has trouble receiving, then you
must re-record the OGM to include it.
Special line considerations
for U.K.
Using extension telephones
(For U.K. only)
It may be that your premises are already
wired with parallel extension telephones, or
you intend to add extension telephones to
your line, in addition to your machine. While
the simplest arrangement is straightforward
parallel connection, there are some reasons
as to why this arrangement will cause
unsatisfactory service, the most obvious of
which is inadvertent interruption of a facsimile
transmission by someone picking up an
extension telephone in order to make an
outgoing call. Additionally, Fax receive 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.
Such problems can easily be eliminated
however, 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 such a configuration,
this 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 on the next page, and the
recommended master/slave configuration is
shown in figure 2.
This new connection configuration can be
arranged by contacting BT, Kingston upon
Hull Telecommunications, your PABX (PBX)
maintainer or a qualified telephone
installation company as appropriate. Simply
explained, the extension telephone circuit
should be terminated on a normal modular
plug (BT 431A style), which in turn should be
