Installing your headset

Before you connect your headset please ensure that any volume settings on your telephone are turned down to avoid any unnecessary discomfort.

There are two ways of connecting your BT Accord headset to your telephone.

1) Direct connection

If you have a BT Converse, Relate 3000 or any other telephone with a dedicated headset port, simply plug the headset directly into the headset port on your telephone. You do not need to use the configuration box. Features such as mute and volume control will be driven by your telephone. Please refer to the instruction manual for your telephone if you are unsure how to do this.

2) Connection using the configuration box

If you do not have a headset port on your telephone you will need to use the configuration box. The configuration box allows you to connect the headset to your telephone and switch between the headset and handset. Please note that your telephone cord must be fitted with a standard RJ11 plug (this is the type of plug used on most telephones).

Using the configuration box

The headset / handset selection button (no. 1 on diagram 1) lets you choose between using the handset and the headset. When the button is pressed you can use the headset, when it is raised you can use the handset.

Note: When using BT Accord 10 and 20 headsets you will always need to lift the handset to receive or make a call, and replace the handset to end a call.

The mute / talk button lets you place a caller on hold by pressing down to the mute position. The caller will not be able to hear you but you will still be able to hear the caller. To resume the call press the button again.

The configuration box does not need a battery to operate.

1If you have problems such as a high pitched whine or crackling noise whilst using the headset, you may need to change the settings on your configuration box for the headset to work properly with your

telephone / telephone system.

To do this, open the top cover of the configuration box. There are two selector switches marked 1, 2, 3, 4 and A, B, C (No’s 3 and 5 on diagram 1). These selectors create twelve possible settings for maximum compatibility. Try each setting one by one (for example, A+1, A+2, then A+3) until you can hear a clear dial tone through the headset. If more than one setting gives a dial tone then choose the clearest setting.

2If your caller is unable to hear you, check that your mute button is not depressed.

3If you cannot use the handset, check that you do not have the headset mode selected and that you have the handset and headset connected into the correct sockets.

Note: The factory default setting for the BT Accord configuration box is B+4. This works for the majority of telephones.


For your safety we advise that you keep this headset and its components away from any liquids. Do not attempt to effect repairs yourself; seek qualified advice. Always operate at a safe volume level to protect your hearing. Take a break after using the headset for a significant amount of time.
