o not place your BT Synergy
3505 in the bathroom or other
humid areas.
Handset range
The BT Synergy 3505 has a range
of 300 metres outdoors when there
is a clear line of sight between the
base and handset. When there is
no clear line of sight between the
base and handset, e.g. base
indoors and handset either indoors
or outdoors, the range could be
reduced to 50 metres. Thick stone
walls can severely affect the range.
Signal strength
The symbol on your handset
display indicates when you are in
range. When you are out of range,
it flashes and BASE 1 is displayed.
The base station must be plugged
into the mains at all times.
IMPO TANT
o not connect the telephone line
until at least one of the handsets is
fully charged.
The base station must be plugged
into the mains power at all times.
You must charge your handset for
16 hours before you can use it.
Which socket?
Power socket
Telephone line socket
Location
You need to place your BT Synergy 3505 within 2 metres
of a mains power and telephone socket so that the
cables will reach.
Make sure it is at least 1 metre away from other
electrical appliances to avoid interference.
Your BT Synergy 3505 works by sending radio signals
between the handset and base. The strength of the
signal depends on where you site the base. Putting it as
high as possible ensures the best signal.
Setting up
1. Plug the mains power cable into the base. Use the power
supply with the clear plastic end.
The green Power/In use light comes on and the base
announces the default answering machine settings (see
page 10). The message counter comes on and alternates
Getting started 7
5675 BT Synergy 3505 UG [4] 11/11/03 4:02 PM Page 7
between 0and Cuntil the day and time are set.
2. Insert the 2 x AAA NiMH batteries supplied. Then slide
the battery compartment cover into place.
3. Place the handset on the base to charge for at least 16
hours. The red Charging light comes on (the red Charging
light stays on even when the batteries are full charged).
The handset is pre-registered to the base as SYNERGY
HS 1. This is shown on the display. When the handset is
fully charged the display shows a full battery symbol.
4. After 16 hours, plug one end of the telephone line cord
into your BT Synergy 3505 base and the other end into
the telephone wall socket.
Talk/Standby time
Under ideal conditions, fully charged handset batteries
should give about 14 hours talk time or 350 hours
standby time on a single charge.

BATTE Y LOW WA NING
If the handset battery symbol is
empty and flashing, and you hear
a warning beep every minute, you
will need to recharge your handset
before you can use it.
Battery performance
To keep your batteries in the best
condition, leave the handset off
the base for a few hours at a time
(after the initial 16 hour charge).
New NiMH batteries do not reach
full capacity until they have been
in normal use for several days.
Running the batteries right down
at least once a week will help them
last as long as possible.
The charge capacity of
rechargeable batteries will reduce
with time as they wear out, so
reducing the talk/standby time of
the handset. Eventually they will
need to be replaced. New
batteries can be obtained from the
BT Synergy Helpline 0870 605 8047.
Under no circumstances should
non-rechargeable batteries be
used. Use only approved Nickel
Metal Hydride batteries (NiMH)
size AAA capacity 550mAL 1.2V.
Using unapproved batteries will
invalidate your guarantee and may
damage the telephone
