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 2100. It may also
invalidate approval of this apparatus.
To get a replacement Synergy 2100
charging cradle power supply unit –
Item Code 872040 – contact the
Synergy Helpline 0845 602 1041.
There is a slight chance your
phone could be damaged by
an electrical storm. We
recommend that you unplug your
Synergy 2100 from the mains power
and telephone socket during storms.
The Synergy 2100 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 2100
in damp, humid conditions
such as bathrooms. Do not
expose the equipment or batteries to
fire and water.
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
2100 works by sending radio
signals between the base station and
handset. These signals can interfere
with hearing aids, causing a humming
noise.
Synergy 2100 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 2100 at least one
metre away from such appliances to
minimise any risk of interference.
SAFETY INSTRUCTIONS

Setting up
Follow these steps to set up your Synergy 2100 handset and
charger ready for use.
Please note
The Synergy 2100 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).
SETTING UP

for at least 16 hours
Before you use your Synergy 2100 for
the first time, it is important to have
the handset battery fully charged.
We recommend that you leave the
Synergy 2100 on charge for at least
16 hours.

If the handset battery symbol is
empty and flashing, and you hear a
warning beep ever y 10 seconds, you
will need to recharge your handset
before you can use it.
Battery performance
After charging your Synergy 2100
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.
Under ideal conditions, the handset
battery should give about 12 hours
talktime (7 hours in handsfree mode)
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.
