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

Setting up  
Please note that your handset is already  
registered to the base station.  
Plug the line cord into the other socket on the  
underside of the base marked with a telephone  
symbol.  
Plan the location  
Situate your product close enough to the  
WARNING  
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.  
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.  
Once connected, put the plinth back on the  
base to prevent it from rocking on the table.  
Do not situate the product in the bathroom or  
other humid areas.  
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 29).

Connect the power supply and  
switch on  
A

Important  
You must thread the power supply cable  
and line cord through the plinth before you  
connect to the power supply.  
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.  
Plinth  
Plug the power supply cable into the socket on  
the underside of your base. The power cable  
connector and socket are coloured red.

On-Air 1250 Classic user guide ~ 1st Edition ~ 7th August ’01 ~ 4073  
When the battery has been charged for at  
least 16 hours the display will show the  
symbol; you can then connect the telephone  
line cord to the base.  
If you decide on position B, place 2 of the  
rubber feet on the plinth and 2 on the base.  
Plug the power adaptor into the wall socket  
and switch on. When the power is switched  
on, the button on your base will light up.

WARNING  
Battery low 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 battery is charged.  
Answering the phone before the battery is fully  
charged may prevent it from reaching its  
optimum capacity.  
If the handset battery symbol is empty and you  
hear warning beeps, you will need to recharge  
your handset before you can use it.  
Battery performance  
Your handset is supplied with NiMH  
batteries. These need to be initially charged  
continuously for 16 hours to reach full  
charge.  
2
Charge the handset battery  
for at least 16 hours  
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.  
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.  
Helpline  
If you are experiencing difficulty, please call  
the BT On-Air Helpline on 0845 601 2476.  
Fully discharging the batteries at least  
once a week 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 601 2476.

battery by disconnecting the small plug  
inside the battery compartment.  
Connect the plug of the new battery.
