®
All mobile units have a 2.5 mm jack socket on the bottom for connecting a
headset. Use recommended headsets only (see Accessories starting on page 124).
The
Aastra 620d/630d
mobile units have a
Bluetooth
interface (2.0) for operating
corresponding headsets. The
Bluetooth
interface can be used for transmitting
audio data only with a headset.
Safety Precaution
Headsets (earphones and headphones) can produce tones which are very loud
and high. When you are exposed to such tones, this can lead to hearing damage.
Before using a headset, please adjust the volume to the lowest possible level. You
can make these settings for cable-connected headsets in the
>
Audio
>
Volume
>
Headset (cable)
menu (see page 90). Adjust the setting directly on the
device with
Bluetooth
headsets (please consult the device user guide). When tele-
phoning with the headset, adjust the volume – if necessary – slowly.
Aastra 630d : Removing the Cover
The opening of the headset socket is closed with an undetachable cover. If a
headset is not used, please be sure to close the opening to be sure the device can
be operated in accordance with its protection class.
Remove the cover by tugging it out of the housing on the
upper
edge.
Never tug it out on the lower edge!
