The
"Installation" information providedin this User Guide is
for
the
sole use
of
your approvedtelephone installer.
The types
of
telephone covered by this guide including the illuminated panel version
in the 'Off-hook' illumination mode, are approved
in
the United Kingdom under the
no. S/3064/3/P/502732 for connection to a direct exchange line (i.e a line exclusive to
the exchange meter, not a shared
or
party line), to an extension
of
a direct exchange
line or to an extension
on
certain types
of
PBX.
The illuminated panel version (/21XO)
in
the 'On-hook' mode,
is
only
permitted to be
connected to a direct exchange line
when
set to the 1rnA setting. The local exchange
office MUST be informed
of
the installation so that they can disconnect the Line
Testing Equipment that checks for line current. This version
when
set either
in
the
1rnA or SrnA modes, may be connected to any PBX
or
equivalent
equipment
provided it has approval to offer up to this
amount
of
'On-hook' line current.
No
versions are suitable for use
on
party line installations
or
as
extensions to pay phones.

AdditionalFacilities
Any
other usage
will
invalidate
the
approval
of the apparatus
if
as a
result
it
then
ceases
to
comply
with
the
standards against which
approval
was granted.
Connection
is
effected
by
plugging
in
to
the
appropriate
line
socket.
If
your telephone
connection
is
not
fitted
with
new
style
sockets contact
your
approved telephone
installer
or
the
telephone network supplier
(using
the postcard
provided).
If
this
method of connection
is
inadequate because
for
example
the
telephone
is
to
be mounted outside, where new sockets are
not
intended
to
be
used,
arrange
for
your
telephone network supplier
to
directly
connect
the
instrument
(using
the
postcard
provided).
The
telephone should operate
correctly
when connected
to
most compatible
PBXs,
including
those that
use
secondary
dialling
tone.
However
it
cannot
be
guaranteed
that
the
apparatus
will
operate under
all
possible conditions ofconnection.
Any
cases
of
difficulty
particularly
in
the
case of the illuminated panel
versions,
should be
referred
in
the
first
instance
to
your
local
supplier
of
the
instrument.
This
apparatus
is
intended
to
be
internally
accessible
for
installation
purposes,
only
to
authorized personnel
and
must
be
installed
such
that
user
access
is
prevented.
Correct
fitting
and
installation
are mandatory
as
failure
to
prevent such user access
will
invalidate
any
approval
given
to
this
apparatus.
On
the
illuminated
versions
(/21XO)
a
user
definable
text
panel
is
provided.
To
access
this,

front
panel.

a
thin
clear

of
plastic
