Safety information

General

Only use the power supply included with the product. Using
an unauthorised power supply will invalidate your guarantee
and may damage the telephone. The item number for the
mains power supply is 001040.

If Keyguard is active, it is still possible to make emergency
calls to 999 and 112.

Do not open the handset or base station. This could expose

all repairs.

Radio signals transmitted between the handset and base may
cause interference to hearing aids.

This product should not be used near emergency/intensive
care medical equipment and should not be used by people
with pacemakers.

Never dispose of batteries in a fire. There is a serious risk of
explosion and/or the release of highly toxic chemicals.

Cleaning

Simply clean the handset, USB unit and base station with a
damp (not wet) cloth, or an antistatic 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 it’s 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.

Introduction

Your BT On-Air 1800 provides an all-in-one
solution combining telephone, answering
machine and wireless modem for Internet
access.

By plugging the BT On-Air USB unit into your
desktop or laptop computer, you can connect
to the Internet from anywhere in or around
your home without wires.

The proven DECT digital cordless technology
is used for the voice and data communication
between the handset or BT On-Air USB unit,
and the base. The base plugs into your
telephone socket and features a fast 56k
Internet Modem.

Minimum PC requirements

• Windows 98, Me, 2000 or XP.

• Pentium Processor 200MHz.

• 32MB RAM.

• Free USB port (if an exter nal USB hub is
used, it must be mains powered).

• CD drive for installation of software.

Note

The BT On-Air 1800 Wireless Modem is
approved for connecting to Internet Service
Providers supporting V.90 connections. This is
the case for all major ISPs. It does not support
fax send/receive. It also cannot receive
incoming modem calls and therefore does
not support remote access using callback
mechanism.

Setting up

Once connected, put the plinth back on the base
to prevent it from rocking on the table.

There are two positions for the plinth when
joining it to the base, both can be used for desk
mounting and one for wall mounting. Position
A is for desk mounting only and position B is
for desk or wall mounting (see wall mounting
on page 51).

Base and handset

2 Connect the power supply and

switch on.

Plug the power supply cable into the socket on
the underside of your base. The power cable
connector and socket are coloured red.

Plug the line cord into the other socket on the
underside of the base marked with a telephone
symbol.

WARNING

Please take care that the power supply and
telephone line cord are connected to the
correct sockets as incorrect placement could
damage your equipment.

BA

Your handset is already registered to the base.

1 Plan the location

Situate your base close enough to the
telephone and mains power sockets so that the
cables will reach.

The only way to disconnect the product from
the power supply is to remove the power
adaptor from the mains power socket.
Therefore you must ensure you plan the
location so that the mains power is easily
accessed.

Make sure it is at least 1 metre away from
other electrical products to avoid interference.

Do not situate the product in the bathroom or
other humid areas.

plinth

Important

You must thread the power supply cable
and line cord through the plinth before you
connect into the sockets on the base.

10

3 Charge the battery in the

handset for at least 16 hours

WARNING

Under no circumstances should
non-rechargeable batteries be used. Only use
the approved batteries. Using unapproved
batteries will invalidate your guarantee and
may damage the telephone.

Fully discharging the batteries at least once
a month will help them to 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 any BT Shop or from
the Helpline on 0845 300 0156.

Battery low warning

If the handset battery symbol is empty and you
hear warning beeps, you will need to recharge
your handset before you can use it.

Plug the power adaptor into the wall socket and
switch on. When the power is switched on, the

PLAY button on your base will light up green.

Battery performance

Your handset is supplied with NiMH
batteries. These need to be initially charged
continuously for 16 hours to reach full
charge.

Note that the battery charge icon does not
indicate the correct level when the batteries
are first installed. The batteries must first be
fully charged.

4 Connect the telephone line cord

Plug the line cord into the telephone wall socket.

Place the handset in the cradle on the base
station. The handset display will show the
battery symbol. If it does not appear, see Help,
page 48.

When the battery has been charged for at least
16 hours the display will show the symbol.

rubber feet on the plinth and 2 on the base.

After installation, the BT On-Air Monitor
window is displayed.

strength).

➜

Click OK.

The installation is now complete and the
BT On-Air Monitor is displayed.

3 Checking the installation

1

If the signal strength is poor or you cannot
log on, the most probable causes are that your
computer is out of range of the base or that the
base is not switched on. Check that the base
was properly set-up by following instructions
in this user guide and move closer to the base.
If you still cannot log on to the base, see ‘Help’

page 48. (See page 20 for more information on
using the BT On-Air Monitor.)

19

If you already had an Internet connection set-up
on your computer before installing BT On-Air:

If you ticked the Internet connection during
the Internet Connection Settings part of the
BT On-Air installation, then you are now ready
to connect to the Internet. You can now turn to
the next section for instructions on how to use
the modem.

If you do not have an Internet connection
installed or want to update an existing one:

Instructions for setting up an Internet
connection depend on your computer and your
chosen Internet Ser vice Provider. Refer to the
Windows online help on how to set-up an
Internet connection or follow the instructions
given by your Internet ser vice provider.

When installing your new Internet
connection or updating an existing one,
select “BT On-Air Wireless Modem”
within the dial-up networking properties
when prompted for a device to use for
the connection.

4 Setting-up your

Internet connection

Note

The BT On-Air 1800 supports speeds of
56 kbit/s for download from an ISP only.
Upload remains at 33.6 kbit/s.

The actual speed achieved depends on the
line condition and will vary across dif ferent

connections.

20

Using the modem

Note

Your BT On-Air USB unit is powered via
the connection to your computer so, if you
are using a laptop computer, you may notice
a slight reduction in the battery capacity.

Note

If Call Waiting is enabled on your line, any
incoming call will cause an active Internet
connection to drop. You should disable Call
Waiting before making an Internet
connection. Please refer to your network

operator's instruction.

Note

You cannot use the modem monitor while
connected to the Internet.

To use the modem monitor

The BT On-Air Wireless Modem monitor lets
you rename the base, change the system code
and de-register your BT On-Air USB unit.
It also indicates when your BT On-Air USB
unit is in or out of range of the base.

To connect to the Internet

When your modem is installed, you also need
to choose an Internet Ser vice Provider and
set-up a dial-up networking connection on your
computer before you can connect to the
Internet.

If you have not got a connection installed
already, you can get an installation disk by
contacting your chosen service provider.

Your provider will give you instructions
on how to set-up the dial-up networking
connection. When installing your service
provider’s Internet software, select “BT On-Air
Wireless Modem” when prompted for a device
to use for the connection.

Please refer to Help section on page 48 if you
are experiencing problems.

Click on the BT On-Air icon in the system tray.
This is normally at the bottom right of your
computer screen.

Important

The BT On-Air USB unit must be connected
to your computer and the software installed
before you can connect to the Internet.

BT On-Air USB unit
installation

What to do first if installation fails

– unplug the BT On-Air USB unit from

your computer.

– follow Uninstallation instructions on page

23 to check the product is not already
installed. The “BT On-Air 1800 Wireless
Modem” should not appear in the list of
programs installed on your computer. If it
does, remove the program as instructed on
page 23 and carr y on with the instructions
below.

– start the

cleanup

application found on your
BT On-Air 1800 CD-ROM. Click “Yes”
on the dialog box shown. Close cleanup
confirmation box by clicking OK.

– now proceed with installation for your

operating system as detailed in the set-up
section of this user guide.

The installation does not start

Check that the operating system of your
computer is Windows 98, Windows Me,
Windows 2000 or Windows XP.

Check the light on the BT On-Air USB unit

If the light is continuously off:

– check that the BT On-Air USB unit is

correctly plugged into the USB por t of your
computer or into a mains powered USB Hub
(the BT On-Air USB unit does not operate
on a bus powered hub).

If the light is on or blinking:

– follow instructions under “What to do first

if installation fails” if you haven’t already
done so.

– see also help under “USB unit is not

detected by my computer when it is
plugged in”.

USB unit is not detected by my computer
when it is plugged in

The USB port on some computers is not
activated in Windows and needs to be enabled
before first use. Make sure the ‘Universal
Serial Bus controller’ is installed in your
Windows system. This can be checked by
opening the Control Panel.

To check, open the Control Panel
(Start – Settings – Control Panel).

Double-Click on the System icon.

Click on Hardware tab.

Click on Device Manager button and
scroll down list.

The

Universal Serial Bus controller

should be
shown in the device list. If this is not available
refer to your Windows manual or contact the
manufacture of your computer in order to
install new components.

See also help under “The installation does
not start”.

The installation was successful but the
base cannot be found

– is the base switched-on (Play button lit)?
– is the USB unit close enough to the base ?

(typical range is up to 50m indoor and 300m
outdoor but this can be reduced depending
on the environment where the product
is used)

– is the USB unit registered on the base ?

➜

➜
➜

➜

49

Connecting to the Internet

What to do first if installation was
successful but you cannot connect to
the Internet

Check that your USB unit is logged-on to the
base. The BT On-Air Monitor should show
“Logged on as no ...”. If not (“------Not logged­on------” is shown), read Help under “The
installation was successful but the base
cannot be found”.

Check that your BT On-Air 1800 base station
is correctly set-up by pressing the Green
Button on the handset to listen to the line. You
should hear a dial tone. If not, check that the
line cord is plugged in your telephone socket
and in the correct socket on the base.

Check the light on your BT On-Air USB unit:
– If it is continuously ON (not blinking); this

means you are in range of the base. Follow
help under “General check”.

– If it is blinking; you are most likely out of

range of the base. Follow help under “How
do I check that the module is close enough
to the base”.

Check that your dial-up networking connection
has been set to use the BT On-Air Wireless
Modem.

General check

If you are experiencing problems using the
modem after it has been successfully installed
open the BT On-Air Monitor by clicking on the
BT On-Air icon in the system tray (usually
situated at the bottom right hand of your
computer). Check that the signal with the base
is of good quality. Now click About BT On-Air.
If the software versions are correctly shown
for components, (for example, does the RFPI
number on the screen match the number
printed on the label underneath the base) the
problem is likely to be with Windows dial-up
networking rather than BT On-Air. Make sure

your Internet connection was set-up correctly
by following instructions from your ser vice
provider.

How do I check that the module is close
enough to the base

In ideal conditions, your BT On-Air USB unit
will have the same range as the BT On-Air
handset (up to 50m indoor, 300m outdoor).
Where you can hear a dial tone on your
handset and speech quality is good, you
should be able to connect to the Internet.

The quality of the radio link between the base
and the USB unit can be checked on the BT
On-Air monitor screen (double click BT On-Air
icon in the Windows system tray). Check that
you can see a green bar in the signal strength
indicator. The green bar should always be
continuously visible and should not
temporarily disappear. You should be able to
use the wireless modem even if the green bar
is small (poor signal). However a poor signal
indicates you are at the limit of the acceptable
range and you might lose connection if you
move your computer.

If you cannot see a green bar or if you are
experiencing connection problems and the
signal is poor, move your computer and the BT
On-Air USB Unit closer to the base station.

The light on the USB unit does not come on

Check you are within range of the base.
Try moving your computer nearer.

Check that the USB unit is correctly plugged
into your computer or into a mains power

ed

USB hub.

If plugged into a desktop, try moving the USB
unit away from the computer.

Dialling my ISP seems to take longer than
my old corded modem

This is the normal behaviour. Before dialling,
the data module has to establish the radio
communication. This takes a few seconds.

50

Handset

Handset does not charge

– Check that the base station is connected to

the mains power.

– Check that the battery in the handset is

correctly installed (see How to install
a new battery).

How to install a new battery

Slide the handset battery cover on the handset
and check the two-wire cable is plugged in its
connector.

Remote access or VIP features do not work

Remote access and VIP features require their
respective access code to be changed from
their default setting. Refer to the main part of

Software Licence Agreement

THIS LEGAL DOCUMENT IS AN AGREEMENT BETWEEN YOU,
THE END-USER, AND BRITISH TELECOMMUNICATIONS PLC
(BT). BEFORE OPENING THE SEALED ENVELOPE, YOU
SHOULD READ THE TERMS PRINTED BELOW. BY OPENING
THIS ENVELOPE YOU ARE BOUND BY THE TERMS OF THIS
AGREEMENT. IF YOU DO NOT AGREE TO THESE TERMS, YOU
SHOULD RETURN THE CD TOGETHER WITH ANY ITEMS THAT
ARE PART OF THE PRODUCT, SUCH AS MANUALS AND
HARDWARE, TO THE PLACE FROM WHICH YOU OBTAINED
THEM, FOR A FULL REFUND.

This End-User Licence Agreement comes with a BT software
product (Program(s)) and related written materials
(Documentation). The term Program(s) also includes any upgrades,
modified versions or updates of the Program(s) licensed to you
by BT.

BT non-exclusively licenses this copy of the Program(s) to you
as the End-User for as long as you comply with the terms of this
licence. You must read this Agreement carefully.

1. The Program(s) and all copyright in them and the copyright in

the Documentation are protected by United Kingdom copyright
law and international copyright treaty provisions. This Licence is
not a sale of the Program(s) recorded on the CD or any copyright
in them.

2. You must not:

• translate, modify, adapt or create derivative works from the

Program(s); or

• reverse engineer, decompile, disassemble, or attempt to do

so except as expressly permitted by and subject to all the
conditions laid down by law.

3. The Program(s), their code, their structure and all ideas and

principles underlying them are, except where they are in the
public domain, the confidential information of BT or its licensors,
and you must not disclose them or use them without permission.

4. DISCLAIMER AND LIMITED WARRANTY EXCEPT AS

EXPRESSLY SET OUT IN THIS AGREEMENT, THE PROGRAM(S)
AND DOCUMENTATION ARE SUPPLIED TO YOU WITHOUT
WARRANTY OF ANY KIND. BT AND ITS SUPPLIERS DO NOT
WARRANT, GUARANTEE OR MAKE ANY REPRESENTATIONS
REGARDING THE USE, OR THE RESULTS OF USE, OF THE
PROGRAM(S) OR DOCUMENTATION. BT AND ITS SUPPLIERS
MAKE NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE
SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OF
THE PROGRAM(S). IN NO EVENT WILL BT OR ITS SUPPLIERS
BE LIABLE TO YOU FOR ANY CONSEQUENTIAL OR INCIDENTAL
DAMAGES INCLUDING ANY LOST PROFITS OR LOST SAVINGS,
EVEN IF A BT REPRESENTATIVE HAS BEEN INFORMED OF
THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY
ANY THIRD PARTY.

5. BT warrants to its original Licensee that the CD on which the
Program(s) are recorded are free from defects in materials and
workmanship under normal use and service for a period of 90
days from the date of delivery as evidenced by the receipt. BT’s
entire liability and your only remedy under this warranty is, at
BT’s option, either: return of the purchase price; or replacement
of the CD which is returned to BT postage paid with a copy of
the receipt. This limited warranty does not apply to CDs, which
fail as a result of accident, misapplication or abuse not the fault
of BT. If BT replaces CDs, BT will warrant them for the rest of
the original warranty period or 30 days, whichever is the longer.
Your statutory rights remain unaffected by this clause.

6. BT has no obligation to support or maintain the Program(s).

7. BT does not exclude or limit its liability for death or personal

injury caused by its own negligence.

8. This licence shall be construed and governed by English
law. If any part of this Agreement is found void or unenforceable,
the balance of the Agreement remains valid and enforceable
according to its terms.

9. This Agreement automatically terminates if you fail to comply
with its terms. On termination you must destroy or irrevocably
delete all copies of the Program(s) including modified copies.

10. This Agreement may only be modified in writing signed by
a duly authorised representative of BT.

11. BT reserves the right to modify the characteristics of the
Software without prior notice. If the product evolves, your license
does not give you the right to free upgrades.
