Conducting calls with the headset

The handset can be used with a corded and cordless
headset.

Corded headset

You can connect a corded headset to the port on the
side. The headset must have a jack (2.5 mm).
The earpiece inset and microphone functions are acti-
vated 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, forexample,
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 de-register it.
Note:
• Theoretically, third parties can tap Bluetooth
connections.
• To improve protection against unauthorised
tapping, de-register any Bluetooth devices
you no longer require.
During a call, a second caller is not signalled at the Blue-
tooth headset.
