Method of connection
This is connected to the exchange line or
PABX/PMBX (Private Automatic/Manual
Branch Exchange) extension by the new
standard British Telecom plug and socket.
Arrangements for provision of this type of
termination can be made through the
nearest British Telecom Sales Office. The
apparatus may be connected to the
following types of installation. The
apparatus has been approved for use
under the following conditions:
a) This apparatus may be used on
telecommunication systems employing
MF signalling. It is suitable for
connection to a direct exchange line
on the PSTN (Public Switched
Telephone Network) or via a
compatible PBX (Private Branch
Exchange). (Contact the supplier for
an up to date list of compatible PBX’s.)
b) This apparatus is not suitable as an
extension to a payphone or for use on
a party line with shared service. This
cordless telephone has been designed
to operate on radio frequencies which
have been assigned to the exclusive
use of cordless telephones. As the use
of cordless telephones becomes more
widespread users may experience a
reduction in the quality of service
obtainable from this apparatus.
Although this equipment can use either
loop disconnected or DTMF signalling,
only the performance of the DTMF
signalling is subject to regulatory
requirements for correct operation. It is
therefore strongly recommended that the
equipment is set to use DTMF signalling
for access to public or private emergency
services. DTMF signalling also provides
faster call set up.
999 or 112 can be dialled on the
apparatus for the purposes of making
outgoing calls to the BT Emergency (999
or 112) Service.
WARNING:
The apparatus may be unable to make
emergency 999 or 112 telephone calls,
under certain conditions, e.g.
• Radio interference caused by another
cordless telephone operating on the
same radio frequency.
• The portable handset battery needs
recharging, or has failed.
• The portable handset cannot be used
while charging.
• When KEY LOCK is set to ON.
• When the unit is in Direct Call Mode.
Any cases of difficulty should be referred
in the first instance to the supplier of the
apparatus.
NOTE:
If you experience any problems with the
normal use of your apparatus, you should
unplug it from the telephone outlet and
connect a known working telephone in its
place. If the known working telephone still
gives problems, then please contact the
customer service department of your
PSTN operator. If it operates properly,
then the problem is likely to be a fault in
your apparatus. In this case, contact your
supplier for advice. Your PSTN operator
may charge you if they attend a service
call that is not due to apparatus supplied
by them.
