For the handset use only approved Nickel Metal
Hydride (NiMH) rechargeable batteries. Never use

could lead to a short circuit or destroy the battery
casing. Recommended batteries should have a power
rating of 550mAh 1.2V. Batteries are available from the
BT Studio Helpline 08706 058 047.
Do not open the handset or base station. This could
expose you to high voltages or other risks. Contact the
helpline for all repairs.
Radio signals transmitted between the handset and base
may cause interference to hearing aids.
It is recommended that advice from a qualified expert
be sought before using this product in the vicinity of
emergency/intensive care medical equipment.
It is recommended that if you have a pacemaker fitted
you check with a medical expert before using this
product.
Never dispose of batteries in a fire. There is a serious
risk of explosion and/or the release of highly toxic
chemicals.
Safety information

10
Cleaning
Simply clean the handset and base station with a damp
(not wet) cloth, or an anti-static wipe.
Never use household polish as this will damage the
product.
Never use a dry cloth as this may cause a static shock.
Environmental
Do not expose to direct sunlight.
The product may heat up when the batteries are being
recharged. This is normal. However, we recommend
that you do not place the product on antique/veneered
wood to avoid damage.
Do not stand your product on carpets or other surfaces
which generate fibres, or place it in locations preventing
free flow of air over its surfaces.
Do not submerge any part of your product in water and
do not use it in damp or humid conditions, such as in
bathrooms.
Do not expose your product to fire, explosive or other
hazardous conditions.
There is a slight chance that your phone could be
damaged by an electrical storm. We recommend that
you unplug the power and telephone line cord for the
duration of the storm.

11
Setting up
Follow these steps to set up your BT Studio ready for use.
Plan the location
Situate your product close enough to the telephone and
mains power supply sockets so that the cables will reach.
Make sure the product is at least 1 metre away from other
electrical products to avoid interference.
Do not place your BT Studio in the bathroom or other
humid areas.
1 Connect the power supply cable
Plug the power supply cable into the power socket
on your BT Studio base station (Item number
872260). The power light on the base will
come on.
2
Plug the power supply adaptor into
the wall socket

12
Warning
Do not connect the telephone line cord to the phone socket
until your handset is fully charged. This will prevent the
risk of the phone being answered before the batteries are
charged. Answering the phone before the batteries are fully
charged may prevent it from reaching its optimum capacity.
3 Insert the batteries
Insert the two batteries supplied, as indicated on
the markings inside the battery compartment and
slide the battery compartment shut. The handset
display will show . This means one handset is
registered to the base. If you have purchased the
BT Studio Twin the handset will show
-2-
. See
page 15.

13
Warning
Under no circumstances should NiCad or non-rechargeable
batteries be used. Only use the approved batteries. Using
unapproved batteries will invalidate your guarantee and
may damage the telephone.
IMPORTANT
The handset must always be placed on the base
face up. The base station must be plugged into
the mains power socket at all times.
4
Charge the handset batteries for at
least 16 hours
Before you use your BT Studio for the first time
it is important to have the handset batteries fully
charged. Place the handset on the base station.
You will hear a long beep. The red charging light
on the base will come on and the battery and
charging icon will be displayed. Leave the
handset to charge continuously for at least 16
hours to reach full charge.
The handset comes pre-registered but the icon
will flash to indicate that the handset is linking
up with the base. Once link up is successful the
icon will stop flashing and remain steady.
Once the handset is fully charged, the charging
icon will be switched off.

14
Battery levels
Battery low warning
If the handset battery symbol is empty, you will hear a
warning beep ever y 1 minute, you will need to recharge
your handset before you can use it. The handset will
only beep every minute when it is in use. In idle mode
the empty battery icon is displayed.
Out of range warning
When the handset is in use and you go out of range of
the base it will beep every 1 minute and the icon
will flash. Move closer to the base station.
Signal Strength
The BT Studio and BT Studio Twin have a range of up
to 300 metres outdoors and up to 50 metres indoors.
This is in ideal conditions.
Battery performance
Fully discharging the batteries at least once a week will
help them last as long as possible. However, 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 Studio
Helpline 08706 058 047.
Note: Under ideal conditions, the handset batteries should
give about 14 hours talktime or 350 hours standby on a
single charge. Optimum times for talk and standby are
only achieved when the handset batteries are fully
charged.
