Warning
1. Use only the approved battery pack supplied.
Spare batteries – Item Code: 871285 are available
from BT Shops and the Synergy Helpline
0845 650 20 20.
2. Do not try to use any power supply except the
one provided, otherwise you may permanently
damage your Synergy 900. It may also invalidate
approval of this apparatus. To get a replacement
Synergy charger power supply unit (Item Code:
871273) and Synergy base station power supply
unit (Item Code: 871340) contact BT Shops or
the Synergy Helpline
3. There is a slight chance that your phone
0845 650 20 20.
could be damaged by an electrical storm. We
recommend that you unplug your Synergy 900
from the mains power and telephone line socket
during storms.
4. If you wear a hearing aid, please note that the
Synergy 900 works by sending radio signals
between the base station and handset. These
signals can interfere with hearing aids, causing
a humming noise.
5. Synergy 900 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 900 at least one
metre away from such appliances to avoid any
risk of interference.
The Synergy 900 system 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, the
sea) and large metal objects (e.g. radiators,
steel girders and metal partition walls).
6. The Synergy 900 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.
7. We advise against placing these products on
antique, veneered or wooden surfaces as damage
may occur.
8. Do not use the Synergy 900 in damp, humid
conditions such as bathrooms. Do not expose
the equipment or batteries to fire or water.
9. Do not dispose of used batteries with general
household rubbish and do not burn them.
10. Do not use the handsets in places where
there are explosive hazards.
11. Make sure you connect the power and
telephone lines to the correct sockets in the
base station.
12. 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.
5
Setting up follow these steps to get your Synergy 900
ready for use.
1. To plan the location of the base
station
Your Synergy 900 works by sending and
receiving radio signals between the base station
and the handset.
The strength of the signal depends on where
you site the base station. The higher the base
station is located, the better. An upstairs room is
ideal. The following points should be considered:
• It should be within 2 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.
2. Connect the power cable
Plug the power cable into the power socket on
the underside of your Synergy 900. When the
power is switched on, the base station
light comes on.
POWER
3. Install the rechargeable battery in
the handset
Hold the handset with the keypad facing down,
remove the clear plastic directory label cover
and press and slide open the battery
compartment.
Push
BATTERY
Slide
Insert the battery pack inside the battery
compartment and slide the battery compartment
cover shut. Replace the directory label cover.
WARNING
It is recommended that the line cord is not
connected until the handset is fully charged.
This will prevent the risk of the phone being
answered prior to the battery being fully
charged and therefore not working to its
optimum capacity.
6
4. Charge the handset battery for at
least 16 hours
Before you use your Synergy 900 for the first
time it is important to have the handset battery
fully charged. We recommend that you leave the
Synergy 900 Handset on charge for at least 16
hours. Place the handset on the base station.
The
CHARGING light comes on. Your handset
should come pre-registered to the base station
as HSET1. If the display shows REG, you will need
to register the handset manually by following the
simple steps on page 24, “To register a handset”.
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)
Please note that while NiCad rechargeable
batteries 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.
Battery low warning
Your handset display will show the status of
your battery:
• When the charge is low, the battery icon
is displayed.
• When the charge is almost out, you will also
hear a warning beep every 10 seconds (during
a call) in the earpiece. This indicates that the
handset is about to switch off.
Battery performance
After charging your Synergy 900 for the first
time, subsequent charging time for the handset
batteries is approximately 4-5 hours. Batteries
and case may become warm during charging.
This is normal and not dangerous.
Under ideal conditions, the handset battery
should give about 6 hours talktime or 60 hours
standby on a single charge. Please note,
however, that the new NiCad battery, does not
reach its full capacity until it has been in
normal use for several days.
5. Connect the telephone line cord to
the Synergy 900 base station
Plug the line cord into the line socket on the
underside of your Synergy 900.
7
6. Connect the telephone line cord
If you do not have modern phone sockets, call
Freefone
engineer to come and fit the correct type. This
is a chargeable service.
NOTE
Take care that the telephone line cord and
power cable plugs are connected to the correct
sockets. Incorrect placement could damage the
unit.
