Key features
Up to five handsets work from

KEY FEATURES
directory.
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.
Enhanced call clarity
Highly advanced digital
technology (DECT)
ensures much clearer calls than
the older style phones.
Excellent handset range
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.
Keypad guard
This prevents accidental
dialling while carrying the
handset around and also lets you lock
the handset against unauthorised use.
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.

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.
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.

Safety instructions
Use only the approved
battery pack supplied. Spare
batteries – Item Code: 871996
are available from BT Shops and the
Synergy Helpline 0845 602 1041.
Do not try to use any other power
supply except the one provided,
otherwise you may permanently
damage your Synergy 2120. It may also
invalidate approval of this apparatus.
To get a replacement Synergy 2120
base station power supply unit – Item
Code 871997 – contact the Synergy
Helpline 0845 602 1041.
There is a slight chance your
phone could be damaged by
an electrical storm. We
SAFETY INSTRUCTIONS
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.
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.
Do not use the Synergy 2120
in damp, humid conditions
such as bathrooms. Do not
expose the equipment or batteries to
fire and water.
9
Do not dispose of used
batteries with general
household rubbish and do not
burn them.
Do not use the handsets in
places where there are
explosive hazards.
If you wear a hearing aid,
please note that the Synergy
2120 works by sending radio
signals between the base station and
handset. These signals can interfere
with hearing aids, causing a humming
noise.
Synergy 2120 can interfere with other
electrical equipment, e.g. answering
machines, TV and radio sets, clock
radio/alarms and computers if placed
too close. It is recommended that you
place your Synergy 2120 at least one
metre away from such appliances to
minimise any risk of interference.
Make sure you connect the power and
telephone lines to the correct sockets
in the base station.
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.
Setting up
Follow these steps to set up your Synergy 2120 ready for use.
Plan the location of your
Synergy 2120
Your Synergy 2120 works by sending
and receiving radio signals between
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.
1
Connect the power cable
Plug the power cable into the power
socket on your Synergy base station.
Plug the adaptor into the mains power
supply and switch on. The power light
comes on.
Install the rechargeable
2
battery in the handset
SETTING UP
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.
10
Charge the handset battery
0-50%
0%
(flashing)
3
for at least 16 hours
Before you use your Synergy 2120 for
the first time, it is important to have
the handset battery fully charged.
We recommend that you leave the
Synergy 2120 on charge for at least
16 hours.
Place the handset on the base. The red
charging light comes on. The handset
should come pre-registered to the
base station as HS1 and this is shown
in the top right corner of the display.
The battery symbol is also shown.
It flashes during charging. Once the
handset is fully charged, the display
shows a full battery symbol.
Battery low warning.
If the handset battery symbol is
empty and flashing, and you hear
a warning beep every 10 seconds,
you will need to recharge your
handset before you can use it.
Battery performance
To keep your battery in the best
condition, leave the handset off the
base station for a few hours at a time
(after the initial 16 hour charge).
After charging your Synergy
handset for the first time,
subsequent charging time for the
battery is approximately
4-5 hours. Battery and case may
become warm during charging.
This is normal and not dangerous.
SETTING UP
11
Battery levels
50 -100%
100%
Under ideal conditions, the handset
battery should give about 12 hours
talktime or 150 hours standby on a
single charge.
Please note, however, that a new
NiMH battery does not reach its full
capacity until it has been in normal
use for several days.
Please note that while the NiMH
rechargeable battery can be
expected to give years of service
they do not last forever.
Their actual lifespan depends on
how heavily they are used but over
time, their capacity to recharge will
begin to diminish and they will
eventually need replacing.

Technical information
Environment
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

environment where the relative
humidity does not exceed 75%.
It should not be used in bathrooms
or near water.
If the power fails
Alternative arrangements should be
made for access to emergency services.
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.
Connection to the BT telephone

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.
Connecting to switchboards
Synergy 2120 is only approved for use
with a compatible switchboard
including those which do not provide
secondary proceed indication.
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
