Conducting calls with the headset
The handset can be used with a corded and cordless
headset.
Corded headset
You can connect a corded headset via the jack on the
side of the handset. The headset must have a (2.5 mm)
jack plug.
The earpiece and microphone functions are activated
on the headset once it is connected.
Cordless headset
You can use a cordless Bluetooth headset with your
handset. This means your hands are free while making
calls and there are no annoying cables, for example,
when you are working at your computer or when you
are on the road.
Your Bluetooth headset must be registered on your
handset before you can use it for the first time. After
this, you can continue to use your Bluetooth headset
until you decide to deregister it.
During a call, a second caller is not signalled at the Blue-
tooth headset.
Caution:
• If you register a headset, any headset that is
already registered will be overwritten.
• If you would like to use a headset with your
handset that is already registered to another
device (e.g. to a mobile phone), please deac-
tivate this connection before you start the
registration process.
• Theoretically, third parties can tap Bluetooth
connections.
• To improve protection against unauthorised
tapping, deregister any Bluetooth devices
you no longer require.
