4 Quick set-up guide
Where to put your
headset base
• Make sure it’s at least a
metre away from other
electrical appliances to
avoid interference.
• Don’t place in a bathroom
or other humid area or near
excessive heat sources,
moisture, low temperatures
or dust sources.
• Don’t place near noise
sources such as a window
with traffic outside,
motors, microwave ovens,
refrigerators or fluorescent
lighting.
• The product works by
sending radio signals
between the base and the
headset. The strength of the
signal depends on where you
position the base. Putting it
as high as possible can help
give you the best signal.
IMPORTANT
Don’t try to make calls until
the headset battery is fully
charged.

1. Plug the mains power
adaptor into the socket
marked Power on the
back of the base.
2. Plug the other end
into the wall power
socket and switch on.
The base should be plugged
into the mains power socket at
all times.
The battery is permanently
attached to the battery
compartment cover (known as
the battery pack). Do not try
to separate them from each
other.
Only use the supplied
rechargeable battery
pack otherwise you may
damage your product. For a
replacement battery pack,
please call the Helpline on
0800 218 2182*.
Talk/Standby time
Under ideal conditions, the
headset battery should give
up to 8 hours of talk time or
115hrs standby on a single
charge. (This doesn’t mean you
can unplug the base or leave
the handset for this length of
time without charge). When
the headset is not in use ,
recharge it by mounting it on
the headset base.

Quick set-up guide6
Please note that new
rechargeable batteries don’t
reach full capacity until they’ve
been in normal use for several
days.
Battery low warning
The red
light on the top of
the headset will flash every
10 seconds when the headset
is not mounted on the base
to indicate that the battery is
low. If the battery completely
runs out the light will turn off
altogether. You must recharge
the battery by mounting the
headset on the base before
you can use the headset again.
Battery performance
To keep the battery in the best
condition, leave the headset
off the base for a few hours at
a time.
Running the battery right
down at least once a week well
help it last as long as possible.
3 Charge
1. Insert the headset into the magnetic charging
mount on the base and leave to charge for at least
3 hours before use. The
light will illuminate red
to indicate that the battery is charging.
If you ever need to remove the battery pack,
simply insert your fingernail into the grooves on
the side and pull the battery pack out.
4 Connect the headset base
You can use your headset to receive calls through
your telephone line with or without connecting it
to a phone. However, to make a call you will need
to connect to a phone first.
If you need some help, call us on 0800 218 2182* or go to bt.com/producthelp
Quick set-up guide 7
After charging your headset
for the first time, subsequent
charging time for the battery is
approximately 2 hours.
The charge capacity of
rechargeable batteries will go
down over time, which will
reduce the talk and standby
times. Eventually they’ll
need replacing. For details
on how to get a replacement
battery, call the Helpline on
0800 218 2182*. Before
removing the battery pack
for replacement, remove any
headset attachment (earbud
excluded) first.
Using your headset on a
broadband line?
If so, you need to fit an ADSL
microfilter between the phone
line cord and the phone
socket. You can get BT ADSL
microfilters from bt.com/shop
If you use BT Infinity you will not
need to use an ADSL microfilter.
For other types of broadband,
please check with your provider
if a microfilter is required.
Connect your headset directly to a telephone line
(to receive calls only)
Make sure the Corded Handset Connected switch
on the side of the base is set to NO, see page 34.
With this set-up you will only be able to receive
calls using your headset. If you also want to make
calls with your headset you will need to connect
to the telephone line via a phone, see page 8 for
instructions.
Connect one end to
the PSTN socket on
the headset base and
the other to your
telephone wall socket.
