All handsets have a 2.5 mm jack plug at the bottom left for connecting a headset. Only use the
recommended headsets (see Accessories page 101).
The Aastra 620d/630d mobile handsets have a Bluetooth interface (2.0) for corresponding headsets.
With a headset only audio data can be transferred via the Bluetooth interface.
Safety information
Headsets (earphones and headphones) can produce very loud and high-pitched feedback. Exposure
to such feedback can damage hearing. Before using a headset, set the volume as low as possible. For
wired headsets, you can adjust the settings in the menu ❯❯❯ Audio > Volume > Headset (wire). In
the case of Bluetooth headsets, adjust the setting on the device (please consult the User’s Guide for
the device). If you are making a call with the headset, adjust the volume slowly if necessary.

please close the opening so the device can be used in accordance with its protection class.
