Key features
Up to five handsets work from
one base
Enhanced call clarity
Highly advanced digital
technology (DECT)
ensures much clearer calls than
the older style phones.
You can make internal calls
between handsets, transfer
an external caller to another handset
and hold three way calls between two
handsets and an external caller.
Excellent handset range
20 name and number directory
Under ideal conditions you
can use your Synergy 2120
handset at up to 300 metres from
the base station outside, or up to
50 metres inside.
Store up to 20 of your most
important or frequently
dialled names and numbers in the
phonebook. It’s then easy to display
and dial numbers in the phonebook.
Each handset has an individual
directory.
Keypad guard
This prevents accidental
dialling while carrying the
handset around and also lets you lock
the handset against unauthorised use.
Make internal and external
calls at the same time
With the maximum of five
handsets registered to the
base station, your Synergy 2120 lets you
use all of them together. One handset
can be making an external call while
the other four handsets are being used
to make separate internal calls.
Last 5 number redial
Display and redial any of the last five
numbers called from your handset.
5
Different ringing
You can set your handsets to give a
different ring for external callers and
internal callers.
Notepad
Saving you the need of a pen and
paper, you can simply note down a
phone number on your Synergy 2120
handset’s memory during a call. You
can then look the number up later or
add it to the phonebook.
Direct call
You can store an emergency contact
number which will automatically be
called when any button is pressed on
the handset. For example, this can be
useful for babysitters.

Introduction
Your Synergy 2120 has been designed for ease of use and made
to the high standards set by BT.
Please read the instructions carefully
before use and retain this user guide
for future reference.
This user guide applies to both single
and multiple handset systems. The
internal call functions described in
this guide apply only to Synergy 2120
base stations with more than one
handset connected.
DECT
By purchasing the Synergy 2120 you
now own a product which combines
the advantages of cordless operation
with the performance of a high quality
corded telephone. It complies with the
Digitally Enhanced Cordless
Telecommunications (DECT)
standard and offers unparalleled
quality and features.
Important
If you wear a hearing aid, please
note that the Synergy 2120 works by
sending radio signals between the base
station and the handset. These signals
can interfere with hearing aids,
causing a humming noise.
Building up a phone system
You can use up to 5 handsets with your
Synergy 2120 base station without the
need for additional wiring.

Synergy 2120 can interfere with other
electrical equipment, e.g. answering

recommend that you unplug your
Synergy 2120 from the mains power
and telephone socket during storms.
The Synergy 2120 will
produce a certain amount of
heat during operation.
Make sure you connect the power and

in the base station.
Equally, the handset as well as any
additional chargers you purchase can
also become warm during charging.
We advise against placing these
products on antique, veneered or
wooden surfaces as damage may occur.
Clean the handset and base station
with a damp (not wet) cloth or
antistatic wipe. Never use a dry cloth
as this may cause a static shock.
Never spray cleaning fluid directly
onto the telephone.

the base station and the handset.
The strength of the signal can depend
on where you site the base station.
Generally, the higher the base station
is located the better. An upstairs room
is ideal.
The following points should be
considered:
• It should be within 3 metres of a
power socket and phone socket
otherwise extension cables will be
required.
• Try to avoid locations near metallic
obstructions or electrical appliances,
such as TV sets, fridges, computers,
fluorescent lights, radiators, metal
pipes and metal window frames.
Plug the adaptor into the mains power
supply and switch on. The power light
comes on.

battery in the handset
Please note
The Synergy 2120 has a range of up to
300 metres outdoors and up to
50 metres indoors. It is possible that
the range may be affected by being
near water (e.g. large ponds, lakes
and the sea) as well as large metal
objects (e.g. radiators, metal partition
walls and steel girders).
The Synergy 2120 uses a nickel metal
hydride (NiMH) battery pack supplied.
Take care to connect the battery as
shown and replace the battery cover.

Technical information
Connection to the BT telephone
Environment
network
Your Synergy 2120 should be kept free
of dust, moisture, high temperature,
vibration and should not be exposed
to direct sunlight. Do not stand it on
carpets or other surfaces which
generate fibres or place it in locations
which prevent the free flow of air over
its surfaces.
Synergy 2120 is fully approved for
connection to the BT network provided
it is used according to the instructions
in this guide. The telephone lines must
provide Multi-frequency (Touch Tone)
dialling capabilities.
It may be connected to Direct Exchange
Lines and switchboards (PBXs) with
new plan (plug and socket)
arrangements.
Warning
The apparatus is designed to be
operated in a normal office or domestic
environment where the relative
humidity does not exceed 75%.
It should not be used in bathrooms
or near water.
Connecting to switchboards
Synergy 2120 is only approved for use
with a compatible switchboard
including those which do not provide
secondary proceed indication.
If the power fails
Alternative arrangements should be
made for access to emergency services.
If you would like a list of suitable
switchboards, contact BT on 154.
If you do not have a compatible
switchboard, it cannot be guaranteed
that the product will operate correctly
under all possible conditions of
connection. If you have any difficulties,
contact BT on 154.
How many phones can you have?
All items of telephone equipment have
a Ringer Equivalence Number (REN),
which is used to calculate the number
of items which may be connected to
any one telephone line. The Synergy
2120 has a REN of 1. Any other
instrument provided by BT may be
assumed to have a REN of 1 unless
otherwise stated. A total REN of 4 is
allowed.
Generally, Synergy 2120 can be
