WARNING
Do not place your BT3710 in the
bathroom or other humid areas.
Handset range
The BT3710 has a range of 300
metres outdoors when there is a
clear line of sight between the base
and the handset. Any obstruction
between the base and handset will
reduce the range significantly.
With the base indoors and handset
either indoors or outdoors, the range
will normally be up to 50 metres.
Thick stone walls can severely affect
the range.
Signal strength
The icon on your handset display
indicates when you are in range of
the base. When it flashes and you
hear a warning beep, you are out of
range and will need to move closer to
the base.
IMPORTANT
Do not connect the telephone line to
the telephone line wall socket until
the handset is fully charged.
The base station should be
plugged into the mains power
socket at all times.
Getting started
Location
You need to place your BT3710 base within 3 metres of a mains
power socket and 2 metres of the telephone wall socket so that
the cables will reach.
Make sure it is at least 1 metre away from other electrical
appliances to avoid interference.
Your BT3710 works by sending radio signals between the
handset and base. The strength of the signal depends on where
you position the base. Putting it as high as possible can help to
provide the best signal.
Setting up
1. Plug the mains power adaptor (item code 052299) into the
power socket marked on the back of the base and secure
the cable behind the retaining clip. Plug the other end into the
mains power wall socket and switch on. The base will come on
and beep and display 00.
It will default to Answer and record mode.

WARNING
Never use non-rechargeable
batteries. Only use the approved
batteries. Using unapproved batteries
will invalidate your guarantee and
may damage the telephone.
Talk/Standby time
Under ideal conditions, the handset
batteries should give up to 10 hours
talk time or 150 hours standby on a
single charge. (This does not mean
you can unplug the base or leave
the handset for this length of time
without charge).
Please note that new NiMH
rechargeable batteries do not reach
full capacity until they have been in
normal use for several days.
Battery low warning
If the icon is flashing in the display
and you hear a warning beep every
minute during a call, you will need
to recharge your handset before you
can use it.
Battery performance
To keep the batteries in the best
condition, leave the handset off the
base for a few hours at a time.
Running the batteries right down at
least once a week will help them last
as long as possible.
After charging your handset for the
first time, subsequent charging time
for the batteries is approximately
6–8 hours.
The charge capacity of rechargeable
batteries will reduce with time as they
wear out, thus reducing the talk/
standby time. Eventually they will
need replacing. For details on how to
obtain spare batteries, call the
BT3710 Helpline on
0808 100 6556*.
2. Remove the protective film from the handset screen and
activate the batteries by pulling the plastic tab away from the
back of the handset.
Rechargeable batteries
already fitted
Remove this tab
and charge batteries
for 24 hours before use.
3. Place the handset on the base to charge. It will beep when
placed in and the battery icon on the handset will flash
to indicate charging. You should let the batteries charge
continuously for at least 24 hours. The batteries and case may
become warm during charging, this is normal.
The main handset is pre-registered to the base as Handset 1.
This is shown on the display. When the handset is fully charged
the display will show .
4. After 24 hours plug the telephone line cord into the telephone
wall socket.
Note: If you ever need to remove the batteries, simply slide open
the battery compartment cover and using the finger holes grip
the batteries and pull them out.
BT3710 multipack users only:
If you have purchased a BT3710 multiple pack, you will need to
prepare any additional handsets and chargers for use.
Place each BT3710 charger within reach of a mains power wall
socket.

If you need some help, call us on 0808 100 6556* or go to bt.com/producthelp
For each additional handset and charger:
1. Plug the mains power adaptor (item code 052300) into the
power socket on the back of the charger and secure the cable
behind the retaining clip. Plug the other end into the mains
power wall socket and switch the power on.
2. Remove the protective film from the handset screen and
activate the batteries by pulling the plastic tab away from
the back of the handset.
The display will show the handset number, 2, to show it is
registered to the base.
3. Place the handset on the charger. It will beep when placed
in and the battery icon on the handset will flash to indicate
charging. You should let the batteries charge continuously for
at least 24 hours.
Any additional handsets supplied as part of a multipack
are pre-registered to the base. So, once charged, are ready
for use.
