Introduction  
Your BT On-Air 1800 provides an all-in-one  
solution combining telephone, answering  
machine and wireless modem for Internet  
access.  
Minimum PC requirements  
• Windows 98, Me, 2000 or XP.  
• Pentium Processor 200MHz.  
• 32MB RAM.  
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.  
• Free USB port (if an external USB hub is  
used, it must be mains powered).  
• CD drive for installation of software.  
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.  
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.  
Safety information  
General  
polish as this will damage the product. Never use a dry cloth  
as this may cause a static shock.  
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.  
Environmental  
Do not expose to direct sunlight.  
If Keyguard is active, it is still possible to make emergency  
calls to 999 and 112.  
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 open the handset or base station. This could expose  
you to high voltages or other risks. Contact the helpline for  
all repairs.  
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.  
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.  
Do not submerge any part of your product in water and do  
not use it in damp or humid conditions, such as in  
bathrooms.  
Never dispose of batteries in a fire. There is a serious risk of  
explosion and/or the release of highly toxic chemicals.  
Do not expose your product to fire, explosive or other  
hazardous conditions.  
Cleaning  
Simply clean the handset, USB unit and base station with a  
damp (not wet) cloth, or an antistatic wipe. Never use  
household  
There is a slight chance that your phone could be damaged  
by an electrical storm. We recommend that you unplug the

Setting up  
Base and handset  
Your handset is already registered to the base.  
plinth  
1
Plan the location  
Plug the power supply cable into the socket on  
the underside of your base. The power cable  
connector and socket are coloured red.  
Situate your base close enough to the  
telephone and mains power sockets so that the  
cables will reach.  
Plug the line cord into the other socket on the  
underside of the base marked with a telephone  
symbol.  
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.  
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.  
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.  
Once connected, put the plinth back on the base  
to prevent it from rocking on the table.  
2
Connect the power supply and  
switch on.  
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).  
Important  
You must thread the power supply cable  
and line cord through the plinth before you  
connect into the sockets on the base.

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.  
Rubber feet  
Hold the black plastic square between thumb  
and forefinger and peel off individual feet  
from backing sheet as shown. These are to stop  
your base from moving and to protect your  
work surface.  
When the battery has been charged for at least  
16 hours the display will show the symbol.  
If you decide on position B, place 2 of the  
rubber feet on the plinth and 2 on the base.

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.

Charge the battery in the  
handset for at least 16 hours  
Battery performance  
Your handset is supplied with NiMH  
batteries. These need to be initially charged  
continuously for 16 hours to reach full  
charge.  
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.  
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.  
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

Connect the telephone line cord  
talk/standby time of the handset. Eventually  
they will need to be replaced. New batteries  
can be obtained from any BT Shop or from

Plug the line cord into the telephone wall socket.

• if you are logged on to the base station  
(Status column),  
• the quality of the radio signal between the  
base and the BT On-Air USB unit (Signal  
strength).  
18  
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.)  
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 different  
connections.

Setting-up your  
Internet connection  
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 Service Provider. Refer to the  
Windows online help on how to set-up an  
Internet connection or follow the instructions  
given by your Internet service 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.  
19  
Using the modem  
If you have not got a connection installed  
already, you can get an installation disk by  
contacting your chosen service provider.  
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.  
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.  
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.  
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.  
Important  
The BT On-Air USB unit must be connected  
to your computer and the software installed  
before you can connect to the Internet.  
Note  
Make sure the base has been plugged into the  
mains and connected to the telephone line.  
You cannot use the modem monitor while  
connected to the Internet.  
Click on the BT On-Air icon in the system tray.  
This is normally at the bottom right of your  
computer screen.  
To connect to the Internet  
When your modem is installed, you also need  
to choose an Internet Service Provider and  
set-up a dial-up networking connection on your  
computer before you can connect to the  
Internet.

BT On-Air USB unit  
installation  
USB unit is not detected by my computer  
when it is plugged in  
What to do first if installation fails  
– unplug the BT On-Air USB unit from  
your computer.  
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.  
– 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 carry 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.  
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 UniversalSerialBuscontroler  
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.  
The installation does not start  
Check that the operating system of your  
computer is Windows 98, Windows Me,  
Windows 2000 or Windows XP.  
See also help under “The installation does  
not start”.  
Check the light on the BT On-Air USB unit  
If the light is continuously off:  
The installation was successful but the  
base cannot be found  
– check that the BT On-Air USB unit is  
correctly plugged into the USB port of your  
computer or into a mains powered USB Hub  
(the BT On-Air USB unit does not operate  
on a bus powered hub).  
– 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)  
If the light is on or blinking:  
– follow instructions under “What to do first  
if installation fails” if you haven’t already  
done so.  
– is the USB unit registered on the base ?

your Internet connection was set-up correctly  
by following instructions from your service  
provider.  
Connecting to the Internet  
What to do first if installation was  
successful but you cannot connect to  
the Internet  
How do I check that the module is close  
enough to the base  
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 logged-  
on------” is shown), read Help under “The  
installation was successful but the base  
cannot be found”.  
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.  
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.  
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.  
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”.  
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.  
Check that your dial-up networking connection  
has been set to use the BT On-Air Wireless  
Modem.  
The light on the USB unit does not come on  
General check  
Check you are within range of the base.  
Try moving your computer nearer.  
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  
Check that the USB unit is correctly plugged  
into your computer or into a mains powered  
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.

Handset  
The BT On-Air icon in the Windows system  
tray has disappeared although the  
software was not uninstalled  
Handset does not charge  
– Check that the base station is connected to  
the mains power.  
This can happen if you cancel un-installation  
or if you close down the BT On-Air application  
other than by clicking the “Close” button.  
To restore the icon, go to the Windows Start  
Menu, select “Programs”, then “BT On-Air  
Modem”, and finally “BT On-Air Modem”  
– 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.
